D values, L values, N values: A discussion about soundproof room performance metrics that anyone can understand.

What I will explain this time is focused on three values: "D value," "L value," and "N value/NC value"!

This time, I will discuss the numbers that cannot be avoided when talking about the performance of soundproof rooms. The "D value" is probably the most commonly seen number when considering building a soundproof room. Formally, it is called "Sound Pressure Level Difference." The larger the number, the higher the sound insulation performance. Next, there is the "L value," which is often seen in apartments and similar settings. This refers to the "Floor Impact Sound Level," which measures the impact sound between floors of adjacent rooms. A larger number indicates a greater impact. The "N value" and "NC value" refer to the "Indoor Noise Level," which quantifies external noise and equipment noise such as plumbing. Both are used similarly, but the term "NC value" is specifically used to distinguish steady noise, such as that from air conditioning. *For more details, you can view the related links on the blog. *For further information, please refer to the PDF document or feel free to contact us.

During the rainy season... Is the humidity inside the soundproof room okay?

During the rainy season... Is the humidity inside the soundproof room okay?

In addition to the pitch and resonance of the sound, let's make sure to manage the humidity in the soundproof room properly to help preserve the important instruments themselves!

This time, I would like to talk about the humidity in soundproof rooms and its impact on musical instruments. Generally, "dryness" is said to be a major enemy for all types of instruments, but excessively high humidity is also not a good environment for instruments. To conclude, it is said that a humidity level of around 50% is appropriate for all instruments. For large instruments like pianos, which cannot be easily moved once installed, it is recommended to carefully design the layout of the instruments and equipment when creating a soundproof room. Since the soundproof rooms from Environmental Space are all custom-made, they can be appropriately designed according to the shape and layout of your room. For those of you considering a soundproof room, please feel free to consult with Environmental Space. We will propose a soundproof room that will delight you and your precious instruments. *You can view detailed content of the blog through the related links. *For more information, please refer to the PDF materials or feel free to contact us.

Regarding the price of soundproof rooms: The reason it is not offered as a package deal.

Regarding the price of soundproof rooms: The reason it is not offered as a package deal.

I will introduce the items we actually ask about the soundproofing construction costs and explain why those questions are necessary!

When everyone thinks about wanting to create a soundproof room, the first thing they want to research along with sound insulation performance is likely the cost and price. For those who call and say, "I want to create a soundproof room," I always ask them the reason. Sometimes I receive inquiries like, "I want to create a soundproof room because the neighboring room is too noisy for me to sleep," but there are cases where I suggest consulting with the management company first, as there may be solutions that do not burden the customer. The method and degree of soundproofing vary depending on the sound pressure and frequency of the instruments. Depending on whether it is a residential area, a busy street, or along a main road, we can estimate the surrounding noise levels, and the soundproofing effectiveness varies based on the building structure, whether it is wooden or reinforced concrete (RC). Additionally, when creating a soundproof room, the load must always be taken into consideration. If you are thinking about wanting to create a soundproof room, we offer free consultations and estimates. Please feel free to contact us. *You can view the detailed content of the blog through the related links. *For more information, please refer to the PDF materials or feel free to contact us.

Is 'complete soundproofing' impossible? - The mechanism behind the 'inaudible' in soundproof rooms.

Is 'complete soundproofing' impossible? - The mechanism behind the 'inaudible' in soundproof rooms.

Sound is essentially caused by the vibrations of objects! The sound level defined as a value is called sound pressure level!

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.

Control the sound's resonance! "Reverberation time" is one guideline.

Control the sound's resonance! "Reverberation time" is one guideline.

This is an explanation using a table that shows the guidelines for reverberation time! I will introduce the definition of "reverberation time."

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. [Contents] ■ What is "reverberation" in the first place? ■ Definition of "reverberation time" ■ Various depending on the location! Explanation of suitable reverberation times *You can view the detailed content of the blog through the related links. *For more information, please refer to the PDF materials or feel free to contact us.

The relationship between the "human ear" and "audible frequencies."

The relationship between the "human ear" and "audible frequencies."

Even though they should be the same size, why do they not sound the same size? An explanation about frequency and "perceived sound."

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.

The deep bass of music heard from apartments and condominiums.

The deep bass of music heard from apartments and condominiums.

Focus on the deep bass of music! An explanation of "airborne sound" and "solid-borne sound."

This blog introduces noise troubles in collective housing such as condominiums and apartments. 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. [Content] ■ The sub-bass that can be heard night after night ■ Why sub-bass cannot be blocked by earplugs *For more details, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.

Is it dangerous if you don't know!? Four effects of noise.

Is it dangerous if you don't know!? Four effects of noise.

Noise poses hidden dangers. Unknowingly, it can lead to irreversible consequences... Let's take early measures to "avoid danger"!

■Even if we simply say "sound," there are various types of sounds. Sound can sometimes soothe our mood, but conversely, it can also be unpleasant and, in severe cases, have harmful effects on the human body. ■The "sounds" we casually listen to every day may also harbor dangers. ■Since "sound" is abundant in our surroundings, we may not usually be aware of it, but let's first recognize the impact of noise.

Indoor sound adjustment

Indoor sound adjustment

Adjust the reverberation time according to the size and purpose of the room to create an acoustic environment where "good sound" resonates.

Environmental Space Co., Ltd.'s soundproof rooms utilize the original design sound-absorbing panel "KSA Panel," allowing for easy adjustment of reverberation time according to the size and purpose of the room. The "KSA Panel" applies the technology of sound traps designed for absorbing low frequencies, which are installed in the walls and ceilings of professional recording studios. In Environmental Space's soundproof rooms, piano rooms, and karaoke rooms, we carefully listen to any requests and carry out the construction accordingly. We provide consulting with thorough explanations of sound pressure levels and other details. 【Features】 ■ Uses the original design acoustic panel "KSA Panel" ■ The suspended sound-absorbing body can absorb low frequencies due to panel vibration ■ On-site construction can be completed in a short time ■ By changing the panel shape and color, it can accommodate your preferred interior design *For more details, please refer to the PDF materials or feel free to contact us.

Fundamentals of Sound

Fundamentals of Sound

An explanation of the basics of sound using diagrams. Please download and take a look at our catalog.

"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." Please feel free to download and take a look. *For more details, please refer to the PDF document or feel free to contact us.

Three points to consider when building a soundproof room.

Three points to consider when building a soundproof room.

From the piano soundproof room to the audio room. Here are essential points to consider when building a soundproof room.

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.*

Noise level that does not disturb the neighbors.

Noise level that does not disturb the neighbors.

How much soundproofing is needed to avoid disturbing the neighbors? I will introduce it using a graph.

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." Please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.

Searching for a house where musical instruments can live: What are the important elements in design and construction beyond soundproofing?

Searching for a house where musical instruments can live: What are the important elements in design and construction beyond soundproofing?

Can we secure the delivery route for large instruments? An explanation of the points to consider when placing instruments in an apartment.

Musicians do not choose properties based solely on location or layout like the general public; instead, they first consider the instruments, which significantly narrows down their options. When placing instruments in an apartment, soundproofing is essential, but it’s not just about "preventing sound leakage." One must also consider whether the building structure can withstand the weight of the soundproof room and instruments, whether there is enough space for realistic instrument playing, and whether there is a clear path for moving large instruments in. In this blog, we will explain important elements related to design and construction, not just soundproofing. *For more details, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.
