Architectural Acoustics Secrets Exposed! Here’s the Details Of Sound Design

As you imagine acoustics you’re likely to think about concert venues. However, musicians aren’t the only people who benefit from great audio-visual quality.

Acoustic insulation board for buildings are vital to making sure that sounds are transmitted clearly and efficiently. They are crucial in maintaining a calm environment in areas like libraries or museums, or to make sure that noises aren’t overly excessive in venues.

The loudness of the environment can cause anxiety, stress and blood pressure. It can also make people more at risk of developing heart disease. A well-designed structure that has the right acoustics could affect a person’s mental health and overall wellbeing to the best of their abilities.

It’s true that good sound quality is essential in nearly any situation, and that’s why it’s crucial to ensure they are in good shape from the start. It’s easier to integrate solid acoustics into your project right from the start in the conception phase to the construction stage as opposed to having to modify things later.

What Exactly Is Architectural Acoustics?

Acoustics is a specific branch of physics focused on the study of sound and how it is created as well as how it is transmitted, controlled and received, as well as the results from this method. In relation to the architecture field, it is the practice of using design for buildings and construction techniques to harness the power of sound to the maximum impact.

Architectural acoustic floor insulation involves the design of the structure of a building so that it can control the way sound waves reverberate from its interior so that they are clearer by amplifying sound in locations that are appropriate for doing this, and decreasing noise levels in areas where this is advantageous.

This involves analysing a variety of elements, including the geometric shape of the space and the building materials and their ability to absorb sound or enhance it. Mechanical systems also play a part for example: Motors, fans and other mechanical parts generate noises that can cause distracting noises, and could disrupt the transmission of information.

Architectural designers take these elements into consideration when designing structures that have the right forms, surfaces and mechanical systems to help distribute sound efficiently and effectively.

It’s interesting to note that research has discovered that there is a perfect room design for optimal acoustics. It’s a rectangular shape and built using the Golden Ratio (8 feet in height and 12.8 feet across in 18.64 feet in length).

When it comes to the materials that are soft, such as flooring, insulation made of fibreglass and foam padding absorb sound effectively, whereas more robust materials like brick and concrete tend to reflect sound. Wood is a good reflector of sound however, should holes be drilled into it, it will also absorb sound.

Mechanical components can be placed an appropriate distance from rooms in order to limit their impact on acoustics and noise-controls, such as insulation and technology could also be used.

What Is The Purpose Of Acoustic Design?

As we’ve previously mentioned, the right design of acoustics serves many purposes, such as the following:

  •         The reduction of anxiety and stress levels
  •         Hearing protection
  •         Helps to focus
  •         In reducing or minimising hypertension
  •         Enhancing speech communication
  •         Maximising the enjoyment from music performances

Communication, specifically, can be improved by using excellent acoustics due to the interaction of a variety of aspects. Acoustic insulation that is properly designed and designed help in the clarity of speech and at the same time cutting down on noise that is distracting, lessening distractions and assisting in concentration. Eliminating loud noises is also a major contributor to the retention of hearing throughout the course of time.

Architectural Acoustic Techniques

When you’re designing your auditorium or library as well as a music venue, you need to know the characteristics of sound, the way it’s transmitted, as well as the techniques that you can use to control the sound’s transmission.


Reverberation sounds like reflection does to light. Also called resonance, reverberation is the term used to describe the length of time it takes for a sound to disappear.

Sound waves bounce off surfaces in indoor areas, like wall panels and ceiling tiles as they build up, the noise bounces back decreasing its clarity and making it difficult to comprehend. It’s distinct from an echo, which is when there’s a delay in between the sound source and the more faint echo.

The combination of these two will create the illusion of a single sound wave that bounces back and forth and creates distortion. Reverberation time refers to the amount of time it takes for a sound’s decay by 60 decibels (decibels) following abruptly ended. The longer the reverberation period the louder and more muffled the room may sound.

Buildings With Reverberation

Sometimes, you’ll want to create a space that has more reverberation. It can increase the warmth and feel of music. Therefore, the concert halls and symphony halls are most likely to be built with greater reverberation time.

If high reverberation time is built into the hush soundproofing of a concert venue they can provide an even more powerful and rich experience. If they’re not, the music will appear smaller and less enveloping.

Buildings Without Reverberation

In contrast, if your space is intended predominantly for speaking purposes for example, a lecture hall, then you’ll need to design acoustics that have smaller reverberation times to maintain the clarity. Inadequately, it could cause confusion and anger between the attendees trying to figure out the meaning of the message being spoken.

If low reverberation is used in a space, like a conference room the listeners will stay more engaged because it takes less effort to listen and comprehend the message. If it’s not, they might “tune out” because of frustration, or feel exhausted after needing to concentrate, not only on the message but also on listening to the message.

Sound Absorption

Sound absorption is the characteristic present in various materials that can reduce reverberation time by taking in sound energy and reducing the volume of sound. In removing noise that is not needed the materials improve the sound quality of the room.

Buildings That Have Sound Absorption

It’s a good idea to have sound-absorbing materials in spaces designed to be used for speaking like conference rooms and lecture halls. As we’ve mentioned, various kinds of materials reflect or absorb sound in different levels.

For example, concrete that is smooth can absorb only 2percent of sound while reflecting the rest 98 percent. On the other hand, an Acoustic panel, which is composed of glass fibres covered in fabric, then affixed on the furring (wooden strips) and with airspace behind it could absorb 75 percent of sound that enters it.

The inclusion of ceiling tile insulation into the design of a building can help to create a cleaner more uncluttered sound by reducing reverberation and absorption of sound before it has chances to bounce off. It can create a quieter, more peaceful environment.

Buildings Without Sound Absorption

Structures that don’t have sound absorption can be prone to excessive reverberation as there is nothing to eliminate any sound that enters the room prior to it bounces suspended ceiling systems for a more raucous and more crowded space. This makes it difficult to hear the spoken word as well as make it more difficult to concentrate, and contribute to the stress levels that result from it.
