• Soundproofing/Shielding Unit

When building a soundproof room, the three key points are: "that sound leaking outside is not a problem," "that there is little external noise or equipment noise, making it quiet," and "that there are no excessive reverberations or reflections that degrade sound quality inside the room." The sound in a soundproof room is transmitted through airborne sound (transmitted sound) and solid-borne sound. Solid-borne sound refers to sound that propagates from the feet of a piano through the floor, as well as sound that enters walls, ceilings, and floors, propagating within the objects and radiating into adjacent rooms. For solid-borne sound, sound insulation and vibration isolation structures (floating sound insulation layers) are essential. In our catalog, we explain topics such as "what soundproof structures for soundproof rooms are," "sound pressure levels by instrument," and "the importance of frequency analysis," using diagrams and graphs. Please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.*

• Soundproofing/Shielding Unit

The conditions for a soundproof room are: (1) There should be no issues with sound or vibrations leaking outside. (2) There should be little external noise or equipment noise, making it quiet. (3) There should be minimal equipment noise, ensuring a quiet indoor environment. Sound insulation considers both the sound leaking from the room to the outside and the sound entering from outside. In the case of a piano room, it is important to ensure that the sound and vibrations leaking from the inside do not disturb adjacent rooms or neighbors. Box-in-box soundproofing construction involves turning the entire target room into a soundproof room. This construction not only floats the soundproof room from the building's structure to prevent vibration transmission but also suppresses sound leakage points (such as air conditioning, lighting, and power sources), ensuring high sound insulation performance. The soundproof rooms from Environmental Space are all custom-made. They can be freely designed regardless of size, room shape, or the presence of columns, beams, or windows. Construction that pays attention to the ceiling and floor tailored to the size of the piano and the design of the room is possible. Professionals in sound who have handled various soundproofing projects will carry out optimal reverberation adjustments and construct a comfortable soundproof room. We also provide solid support for apartments, single-family homes, new constructions, basements, and renovation projects.

• Interior construction

In recent years, there have been many complaints regarding drum and other instrument practice rooms that were designed and constructed without consulting experts, and a common issue among these complaints is the lack of vibration control. Particularly for percussion instruments, since the volume of the sound produced cannot be adjusted, proper design and construction by specialized contractors is necessary. At Environmental Space, we design and construct instrument performance spaces tailored to our clients' needs, ranging from drum practice rooms for private residences to professional practice studios, ensuring they are user-friendly and comfortable. Soundproofing is considered from both the perspective of sound leaking from the room to the outside and sound entering from the outside, but in the case of drum practice rooms, it is crucial to ensure that the sound and vibrations produced indoors do not disturb adjacent rooms or neighbors. The soundproofing performance of a room is evaluated using a rating called the D-value, and the relationship between the D-value and perceived sound is roughly as shown in the table below. This evaluation applies to general residences, and for drum practice rooms, it tends to be about two ranks lower. The required soundproofing performance varies depending on the usage conditions of adjacent rooms, but a target value of around D-75 to D-65 is ideal. Especially in multi-unit housing, even faint sounds from percussion instruments can lead to complaints, making adequate measures essential.

The most important thing when creating a karaoke room is to ensure that it does not disturb the neighbors or external facilities, while providing a comfortable space for singing. In recent years, there have been many complaints from karaoke facilities that were designed and built without consulting experts, and many of these have been renovated afterward. Renovations after opening not only incur costs but may also not provide sufficient measures. In environmental spaces, we prioritize soundproofing and livability for karaoke rooms in both private homes and commercial facilities. We design easy-to-use and comfortable environments, from karaoke rooms that utilize professional studio design techniques and the aesthetics of commercial space design to areas such as lobbies and front desks.

In recent years, condominiums are mainly built with RC (reinforced concrete) structures. While RC has better soundproofing performance compared to wooden or S (steel) structures, due to the nature of closely situated residences, it can be said that condominiums have a more sensitive environment regarding noise compared to single-family homes. Various lifestyles coexist in condominiums, and the times when residents are active can vary widely. Additionally, many newly constructed condominiums emphasize high sound insulation, leading residents to believe that a quiet condominium will be reassuring; however, the quietness of their own unit can make them more aware of surrounding noise. If creating a soundproof room in a condominium could solve various noise issues and provide a free space without disturbing others, it would be incredibly comfortable. Here, we will introduce optimal soundproofing measures, including methods other than soundproof rooms, tailored to various noise concerns in condominiums.

As it gets warmer, many people may feel the urge to move their bodies outside. In fact, it seems that the number of people starting to play golf has surged during the COVID-19 pandemic. When the ball goes into the cup, a pleasant sound of "clink!" resonates, but did you know that this sound is unique to Japan? While it is common overseas to use resin cups, in Japan, metal cups are the norm. Moreover, many of them are made of stainless steel and equipped with a device called a "reflector" that amplifies the sound, making them several times more expensive. Why do we go to the trouble of installing such expensive cups? Imagine this: on a silent course, all eyes are on the small ball on the green, and the white ball is drawn into the cup, "clink!" Isn't there a difference in the excitement when that "clink!" happens versus when it doesn't? This is not just a figment of your imagination; at that moment, the secretion of dopamine is being stimulated in the brain. *You can view more details on the blog through the related link. *For more information, please refer to the PDF document or feel free to contact us.

In this blog, we introduce "sound insulation," which is inextricably linked to soundproofing. Sound insulation works by "reflecting" sound that travels through the air, thereby blocking it. Commonly used materials include steel plates, concrete, and gypsum boards. Upon seeing the names of these three materials, some of you may have thought, "They all seem heavy." That's correct; the characteristic of these materials is that they are "dense and heavy." In physical terms, this is expressed as "having a large mass per unit area," and the greater this mass, the more effective the reflection, resulting in higher sound insulation effectiveness. [Content Overview] - Soundproofing should be considered as a combination of sound insulation and sound absorption. - The effectiveness of sound insulation is influenced by the mass of the material. - By looking at the "D value," you can grasp the general sound insulation performance. - Remember the principles of sound insulation and sound absorption to find soundproofing measures that suit you. *For more detailed content, you can view it through the related links. *For more information, please refer to the PDF materials or feel free to contact us.

In this blog, we introduce one of the important aspects of our soundproofing work, "sound absorption." Soundproofing can be broadly divided into sound insulation and sound absorption. While the term "soundproofing" is generally a conceptual one, "sound absorption" refers to one of the methods of soundproofing. By using materials that absorb sound, known as "sound-absorbing materials," we contribute to soundproofing, with the main effect being the reduction of sound reverberation. These materials are used in music-related facilities such as piano rooms, audio rooms, home theaters, live houses, and studios to create a suitable musical environment by suppressing unnecessary reverberation. *For more details, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.

This blog focuses on "low-frequency sound," which is a type of sound that is difficult for the human ear to hear, even though it is still a sound. Low frequency refers to sounds with a frequency of 100 Hz or lower, and sound is a vibration that is transmitted through gases, liquids, and solids. The number of vibrations per second is referred to as frequency. Generally, sounds with a frequency below 100 Hz are called low-frequency sounds, and among them, sounds below 20 Hz that are difficult for humans to hear are referred to as infrasound. "Low-frequency sound" is commonly present in our daily lives. It is primarily generated by large structures, machinery, and facilities. *For more details about the blog, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.

Have you ever experienced suddenly feeling sleepy while riding the train, accidentally falling asleep, and missing your stop? It's something that everyone has likely gone through at least once. Even if you didn't stay up late the night before and had enough sleep, there are several reasons why you might feel sleepy on the train, all of which relate to the unique vibrations and sounds of the train. There are two main theories: one is that "the vibrations and sounds of the train are similar to those experienced by a baby in the mother's womb," and the other is a phenomenon called "habituation." "Habituation" can be simply described as "the body's acclimatization." It seems to be a term used in psychology, suggesting that when you ride the train, you go through a certain process that leads to feelings of sleepiness.

When it comes to noise troubles, there are many sources, including human voices, footsteps, and household appliances like televisions, but this time we are focusing on the bass sounds of music. The definitions of bass and sub-bass are quite ambiguous, and there are no clear rules. When expressed in Hz (Hertz), sub-bass is generally distinguished as sounds below 100Hz, or in the range of 20Hz to 100Hz, or below 20 to 30Hz.

I have heard that 'plants grow well when they listen to Mozart' and 'dairy cows produce better milk when they listen to classical music.' It is known that good music has a positive effect on living beings, including humans. In the case of prenatal education (where pregnant women strive for mental stability to positively influence the fetus), it may be that the relaxing effect of the mother listening with her ears also reaches the baby in her womb. However, why is it that plants and yeast, which do not have hearing, can listen to music (and even benefit from it)? In this blog, we will explore whether music therapy actually exists by examining the effects of classical music on alcohol and plants. *For more details, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.

This blog introduces the relationship between the human ear and the frequencies that can be heard. Frequency refers to the number of vibrations of sound waves per second, measured in Hertz (Hz). Differences in frequency correspond directly to the pitch of the sound; sounds with lower frequencies (fewer vibrations) are low sounds, while sounds with higher frequencies (more vibrations) are high sounds. The human ear can hear a wide range of sounds, approximately from 20 Hz to 20,000 Hz (or 20 kHz), which is referred to as the "audible frequency range." Within the "audible frequency range," there are frequencies that are easier to hear and those that are harder to hear. In fact, the human ear does not pick up sound mechanically and uniformly like a microphone; rather, the perceived loudness of sounds (or sensitivity of the ear) varies with frequency. *For more detailed information, please refer to the related links. *For further details, please check the PDF materials or feel free to contact us.

"Sound" refers to the auditory sensation caused by sound waves (compression and rarefaction waves) traveling through gaseous, liquid, or solid media. Sound waves are represented by frequency and sound pressure level, which are recognized in hearing as pitch and loudness, respectively. Next, "frequency" indicates the number of times a periodic phenomenon repeats in one second, measured in Hertz (Hz). The human audible frequency range is from 20 to 20,000 Hz. In nature, sounds composed of a single frequency are rare; most contain multiple frequency components. The energy distribution of these multiple frequencies is referred to as "frequency characteristics," which humans can perceive as timbre. Our catalog also explains topics such as "sound pressure level" and "the mechanism of sound recognition."

In this blog, we will talk about the humidity in soundproof rooms. While there are some differences depending on the instrument, it seems best to maintain a humidity level around 50%. In particular, instruments made of wood are strongly affected by humidity. Not only large instruments like pianos, but also wind instruments, string instruments like violins, and percussion instruments like drums require careful management of temperature and humidity. Additionally, speakers and microphones are susceptible to humidity affecting their vibrating parts, and many people tend to manage humidity at a lower level of around 40%. The average humidity in Japan from the rainy season to summer exceeds 75%. Let's effectively use air conditioners and dehumidifiers to manage humidity properly.

In this blog, we discuss the volume of pet vocalizations. The sound of a cat's meow is about 75dB. Of course, there may be individual differences and variations in how they meow, but if the sound is loud enough to wake a sleeping person, it falls into the "noisy" zone. A dog's bark ranges from 90dB to 100dB, which is almost the same as the sound of a train passing under a bridge or an ambulance siren. Furthermore, the attack when they bark "Woof!" adds to the volume, making it quite "noisy" for those who are sensitive to such sounds. If you don't train them not to bark unnecessarily, it could lead to complaints from neighbors. When keeping pets, be sure to take soundproofing measures.
