Due to spending more time at home, both those who make noise and those who are subjected to it have undoubtedly become more sensitive to sound. With schools being closed for an extended period, some people are constantly concerned about the sounds of children's voices and footsteps. Others, who may still be working from home, have started to desire a quieter environment where they can concentrate, even just a little. In this context, a very unfortunate incident stemming from noise from a neighbor has occurred, which I believe everyone is aware of through the news. I think many people have been accumulating stress due to the uncertainty of life with requests to refrain from going out and business closures. Indeed, crime is never acceptable, but I believe everyone has experienced frustration due to noise at least once. In this blog, we will discuss sound and stress. Please take a moment to read it.

There are several key figures that cannot be overlooked when discussing soundproofing. However, many people find numbers challenging. Therefore, in this blog, we will focus on the theme of "understanding the performance values of soundproof rooms through the meanings of words," and we would like to explain the following three particularly important figures. "D value," "L value (LL, LH)," and "N value (NC value)." It may be a bit lengthy, but please stay with us until the end. [Content] ■ Measuring sound insulation performance… D value: the numerical value of sound insulation grade "D" ■ Measuring floor impact sound… L value: the numerical value of sound insulation grade "L" ■ Measuring indoor noise levels… N value/NC value: the numerical value of noise grade "N" *For more detailed information, please refer to the related links. *For further details, please check the PDF materials or feel free to contact us.

For those who started working remotely in the spring, it’s probably about time you’ve gotten used to it. It seems that many people have noticed the benefits of telework, such as "not being swayed by unnecessary tasks, so work progresses smoothly." While it is easier to work, there are also various issues that people realize after trying it out, such as "communication has decreased" and "it's difficult to maintain concentration." In particular, regarding "concentration," I often hear from those living alone that "I thought I could concentrate better at home because it would be quieter, but it turned out not to be the case." Why is that? In fact, moderate noise surprisingly has the effect of enhancing concentration. In this blog, we will discuss sound and concentration. Please take a moment to read it.

I think many people are spending more time at home. One of my friends decided to cook properly since they are spending more time at home, and they boldly purchased a "slightly more expensive" microwave that they had been interested in for a while. The notification sound after heating is often an electronic sound like "beep beep...," but for my generation, the sound of the microwave was "ding!" Why is the sound of the microwave "ding"? In this blog, we introduce the true nature of the microwave sound. Please take a look. [Contents] ■ Curious!

Environmental Space is involved in various jobs related to sound. While we often focus on soundproof rooms for individual clients, such as piano and drum rooms, we actually receive many projects related to soundproofing and acoustics for commercial facilities as well. Just the other day, we were involved in a newly completed cinema project, but unfortunately, the opening has been postponed. The film industry is facing a very harsh reality. In this blog, we aim to provide some bright and enjoyable topics from the film industry, and we will talk about "Chaplin," a 20th-century filmmaker known as the "King of Comedy."

This is a personal story, but I transitioned to a company called "Environmental Space" from a completely different industry, and the first thing that confused me at that time were the terms "soundproofing," "sound insulation," and "sound absorption." I had been using them interchangeably, thinking they all had somewhat similar meanings, but I learned for the first time upon entering this industry that there are actually clear differences between them. I thought there might be others who feel the same way, so in this blog, I would like to return to the basics and clearly explain the differences between these terms. Please take a moment to read it.

There are various sounds that can be described with the word "sound," ranging from pleasant to somewhat unpleasant. In this blog, I will discuss the topic of "somewhat unpleasant sounds." What sounds come to mind when you think of "unpleasant sounds"? Perhaps the first one that pops up is the "sound of nails on a chalkboard." According to one theory, this sound has the same frequency as the cries of a group of monkeys when they sense danger and alert their companions, which is why it is also perceived as unpleasant by humans. As fellow primates, it makes sense that the discomfort is ingrained at a genetic level.

As part of the efforts for "work style reform," telework and remote work have become widely recognized and implemented, but many companies may have accelerated this due to the impact of the COVID-19 pandemic. Looking around, there are some people who say, "Telework? I've been doing that for a while." On the other hand, a common sentiment lately is from those who say, "I suddenly had to start working from home, and I really don't know how to manage it. I'm happy I don't have to ride a crowded train, but I'm struggling to figure out how to work effectively at home." In this blog, we have gathered some common experiences related to telework from such individuals.

Suddenly, is the house you currently live in your own property or a rental? According to the "Housing and Land Statistical Survey" released by the Ministry of Internal Affairs and Communications on September 30, 2019, the percentage of homeowners is said to be 61.2%. Naturally, we often receive inquiries in the environmental space, such as, "I live in a rental apartment, but can I create a soundproof room?" The desire to soundproof is the same whether you own your home or rent it! Therefore, in this blog, I would like to discuss the theme of "Can you create a soundproof room in a rental apartment?"

In this blog, I would like to talk a little about "ventilation." The main work that Environmental Space undertakes is the construction of "soundproof rooms." While it is common to create soundproof rooms for musical performances, have you ever found yourself so focused on practice that your mind became foggy? It might be that the ventilation in the soundproof room was insufficient, leading to a low oxygen concentration in the room. Due to their nature, soundproof rooms are designed to be highly airtight, making it difficult to exchange air compared to regular rooms. It is just right to keep the Lossnay running continuously. Additionally, when not producing sound, I recommend actively ventilating by opening doors and windows. *For more details, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.

In this blog, we are discussing "the loudest sound in the world." The sound pressure level that people generally perceive as "loud" is around 70dB (decibels) or higher. Additionally, for every increase of 10dB, the human ear perceives the sound as being twice as loud. This means that while the difference between 30dB and 40dB and the difference between 100dB and 110dB are both numerically the same at 10dB, they are perceived to be quite different in terms of sensation. It is said that around 100dB, signs of auditory dysfunction, such as pain, begin to appear, and the threshold for tolerable pain is approximately 130dB. *For more details, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.

Recently, with the emergence of various media, it has become easier and more accessible to enjoy concerts and plays, regardless of genre. After all, live performances are exceptional. The ability to fully engage all five senses and enjoy the experience is one of the charms of live music, isn't it? It is often said that "the hall is also an instrument," and concert halls designed for classical music are prime examples of buildings specifically constructed with acoustic considerations in mind. In this blog, we will introduce some representative shapes of concert halls. Please take a moment to read through it.

Fortunately, we receive various inquiries about soundproofing at the Environmental Space every day. One question we always ask is, "What sound (source) do you want to soundproof?" Why? Isn't it enough to just want soundproofing for some reason? The truth is that different sounds have their own characteristics, and these characteristics affect the methods and levels of soundproofing measures. In other words, by specifically identifying the sound source, we can clarify the "volume" and "frequency" of the sound, allowing us to create a plan that achieves the desired soundproofing. There are terms like radio frequency, "low frequency," and "high frequency," and while you might have a general image of them, you may not fully understand what they mean... For those of you, this blog will discuss "frequency."

The "SE" that is essential for movies, theater, and games. You might be tempted to read it as "System Engineer," but this time it refers to "Sound Effects." "Sound Effects" are sounds added as part of the production, including specific environmental sounds that describe the stage environment and conditions, as well as sounds that symbolize the inner thoughts of characters. (From Wikipedia) In this blog, we will introduce several sound effects that can be created from familiar items. Please take a look.

Remote work has become completely ingrained in our lives, and working outside of the office has become the norm. In such situations, it's easy to think that "a quiet place allows for better concentration," but if it's too quiet, our nerves can become overly sensitive, making it harder to focus. By the way, the sound level in quiet places like libraries is around 40dB. A quiet office is about 50dB, and a café is around 60dB. Having moderate background noise helps to block out unnecessary sounds that can disrupt concentration. In this blog, we discuss the reasons why quiet places can actually be unsettling.

When it comes to year-end traditions, Beethoven's "Ninth Symphony" comes to mind. Even those who are not well-versed in classical music have likely heard the chorus of the "Ninth" at least once. It is rare to find a country where the association of "year-end = Ninth" is as strong as in Japan, while in Europe, it is often Handel's "Messiah" that is performed. In this blog, we discuss a little about the influence that the "Ninth," which has been loved for nearly 200 years, has had on subsequent industries. Please take a moment to read it.

Properties located next to train tracks are constantly exposed to the sounds and vibrations of passing trains. For businesses that aim to provide a quiet environment, such noise can be a significant disadvantage, leading to such properties being avoided. However, conversely, it can be said that the surrounding noise is so loud that there is a tendency to be more tolerant of sound. In other words, even if you are making loud noises in your store (classroom), the sound leakage may blend in with the surrounding noise, and many surrounding businesses may not be overly sensitive to it. In this blog, we introduce the idea of turning noise into an ally and the "reverse thinking" of soundproofing. Please take a moment to read it.

December 6th is "Sound Day." On December 6, 1877, the great inventor Thomas Edison successfully conducted the first experiment of recording and playing back sound using the "phonograph." This marked the beginning of the history of audio. In fact, going back 20 years to 1857, a device for "recording" sound was invented by a man named Martinville in France, but unfortunately, it could not "play back" the sound. The phonograph was born from the simple desire not only to record but also to be able to listen to it whenever one wanted. We have received numerous inquiries from customers who love audio and wish to create dedicated soundproof rooms for audio purposes. In this blog, we introduce stories related to audio and records.

Suddenly, do you know what "reverberation time" is? If you are knowledgeable about acoustics or architecture, there is no need for further explanation, but for those who are not, it might be something like, "I can somewhat imagine it, but I don't know the detailed definition...?" For example, when carrying out soundproofing work, there are cases where it is sufficient to simply stop the sound, and there are also cases where one must pay attention to the reverberation of the sound played inside a soundproof room. In this blog, we explain "reverberation time" using familiar rooms as examples. Please take a moment to read it.

The "shishi-odoshi" was originally a device created to scare away animals such as boars and deer that harm agriculture. The sound it makes, described as "corn," is often perceived as pleasant by people, leading to its installation as a decorative element in Japanese gardens, where it is enjoyed and appreciated. Similarly, do you know about the "suikinkutsu," which was initially a practical device but later transformed into a refined aesthetic that embodies the concept of wabi-sabi?

Many of the current houses are primarily made of wood, steel frames, or reinforced concrete (RC). Each has its own advantages and disadvantages, but the sound insulation is highest in the order of RC → steel frame → wood. I remember living in an old wooden apartment during my student days, where I could hear the sounds of my neighbors' lives so clearly that I could even tell what TV program they were watching. Now, it feels like a nostalgic memory. Going back quite a bit, during the Edo period, row houses were the mainstream in Japanese housing, and there was a time when neighborly relationships were the norm. It seems that there wasn't a culture that was particularly concerned about privacy. In this blog, I have summarized the soundproofing qualities of wooden buildings.

The most important thing when creating a theater room is to ensure that it does not disturb external facilities and to achieve a comfortable space. In recent years, there have been many complaints about theater rooms designed and built without consulting experts, and it is not uncommon for these to be renovated later. Renovations can not only be costly but may also not provide sufficient solutions. At Environmental Space, we utilize the technology of professional studio design and the aesthetics of commercial design to create comfortable environments, ranging from home theaters that double as living rooms to fully-fledged theater rooms.

The Kanto region is finally expected to see the end of the rainy season around next week. Many people must be looking forward to being free from drying clothes indoors! In the meantime, events enjoying "wind chimes" are in full swing across various locations. The sight of colorful wind chimes lined up is refreshing just to look at. Wind chimes were originally used as divination tools in China. Known as "senfutaku," they were used to predict good or bad fortune based on wind direction and the sound they made, and during the Nara period, they were brought to Japan as "amulets."

July 25 is said to be the "Establishment Day of the Japan Housing Corporation (1955)." The Japan Housing Corporation was the predecessor of the current "Urban Renaissance Agency (UR Urban Development Corporation)" and provided housing and residential land for workers struggling with housing issues. At that time, public housing was extremely popular and the rent was high, making it an object of aspiration that was difficult to reach. The terms "2DK" and "3DK," which are now commonplace, were first used in public housing.

In recent years, a common topic of conversation during the summer has been, "By the way, there are no mosquitoes this year either." It seems that the temperature at which mosquitoes become active is around 26°C to 32°C. In Japan, where it is no longer uncommon for the maximum temperature to exceed 35°C, it must be a harsh environment for mosquitoes. That said, if you let your guard down, you might suddenly hear that "buzz" right next to your ear in the middle of the night. Why is that sound so annoying?

We are receiving inquiries about soundproof rooms, and I have a feeling that there seems to be an increasing number of customers who are purchasing used homes with the premise of soundproof renovations from the start. In fact, in the metropolitan area, there has been a phenomenon where the number of contracts for used condominiums has exceeded the number of new condominium units supplied for three consecutive years since 2016. While there are many cases of selling renovated homes, it is also common for renovations to be done after purchase. Among these, I wonder how many soundproof renovations are actually being carried out. Additionally, how many people are considering soundproof renovations?

One question that customers who want to create a soundproof room often ask is, "Can it be completely soundproof?" I understand that since you are going through the effort of building a soundproof room, you want it to be thoroughly soundproof. To get straight to the point: From a physics standpoint, it is impossible to reduce sound energy to zero, but it is possible to lower it to a level where it is "inaudible" to the ear. In this blog, I would like to briefly discuss the mechanism of how soundproof rooms can achieve this "inaudible" level. *For more detailed information, please refer to the related links. *For further details, please check the PDF materials or feel free to contact us.

If you handle your instrument with love and care, it won't break easily. Moreover, for a performer, an instrument is a part of their body, so there are likely few opportunities to part with it. However, there are various reasons why you might encounter situations where you "stop using" your instrument, such as "upgrading." What would you do when you no longer "use" your instrument?

A little while ago, from October 10th (Thursday) to 13th (Sunday), there was a global musical instrument exhibition called "Music China 2019" held in Shanghai, China. Did you know that over 2,400 companies from more than 30 countries participated, and the number of attendees exceeded 120,000? Of course, there were brass instruments, string instruments, and traditional Chinese instruments, but this year, I noticed several articles mentioning that manufacturers of "electronic instruments" stood out. Among them, many noteworthy products in the "electronic drum" market were showcased. With that in mind, today I focused on "electronic drums," which we often receive inquiries about regarding soundproofing work in our environmental space. *For more details, you can view the blog through the related links. *For more information, please refer to the PDF materials or feel free to contact us.

The "D value" is a rating defined by JIS (Japanese Industrial Standards) to evaluate sound insulation performance, with a value assigned at a center frequency of 500Hz. The values are ranked in intervals of 5, with larger numbers indicating higher sound insulation performance. To measure the D value of a specific room, it is determined by examining how much the sound (source) generated in that room has attenuated outside of the room (receiver). Our catalog also explains topics such as "the relationship between sound insulation ratings and real-life experiences" and "applicable ratings concerning the average sound pressure level difference between rooms."
