What things need to consider in acoustical interior work
Acoustical architectural work is not only art, but it is the combination of science with art. Acoustical interior space is quite essential as the public space. One should understand the value of acoustic at the construction time and the design and decoration stage. Still, most of us understand its importance after occupying space, and such kind of thought process makes the interior designer job more complicated and challenging. So it is advised to keep an eye on acoustical interior works in construction time and the decoration stage.
The perfect interior should be good as it looks pleasant to the ears as we live there. Acoustical interior work plays a vital role to achieve extensive experience as well as the satisfying experience.
Things should consider designing the acoustical space:
- Requirement of sound for the space
- What is the purpose of the area, and who will use the space
- Privacy, perfect ambience and interaction needed
- Proper sourcing for the sound both inside and outside perspective
- Effect of the fixture, surface material and other kinds of furnishing
- Design option for getting acoustic enhancement
- Proper convenience and well-being for the people who live in the space or working in the space
- Which type of acoustic panel work serves the best purpose
- Apart from it, another kind of limitation and constraints of budgets
Understand the importance of acoustical interior works.
Acoustic links with Sound Communication directly. One can use the acoustic in the small room as well as the large room. Still, it requires proper attention to acoustical engineering while designing large specialized rooms like gyms, auditoriums, and cafeterias.
As we know that, the need for an acoustic consultant is not limited to the room only. Access noise in public spaces can also be irrelevant. Background echo can also be overcome.
Sound is created by many other factors like the vibration of the air and other materials. Sound vibration can generate when we speak, and our vocal cord vibrates, and it creates vibration in the air while it travels to the ears. When the sound becomes higher, the sound waves are closer together, the sound is lower, and the waves are farther apart. The softer sound usually passes through the inner material and curve easily around the thin materials. All the sounds can carry well in the open air or even the tiny holes of walls and ceilings also. Even any tiny hold let you experienced a lot of sound because of the nature of sound.
So, it is necessary to manage the noise generating through the sound using the acoustic panel and it play pivotal role in acoustical interior works. We need to see why an acoustic panel must overcome access sound while constructing the spaced hall.
Why acoustic panel is necessary:
Unwanted sound can be a nuisance, and it is the element to disturb and distract us can harm us psychologically. A large room with the number of people’s conversations can affect the activities with the lot of noise. Sound can be absorbed into the wall as compared to reflecting the sound from the wall. Most of the gyms and cafeterias have built without sound-absorbing material, and they seem very noisy. This can be done with acoustic treatments.
An acoustic panel helps to overcome the noise from the room acts as the sound wave produced through the people conversation. Mobile phone’s ringtones and other kinds of vibrations result from reverberating too long with the surfaces such as drywall, wood and concrete walls. The acoustic panel can absorb such vibration and noise, which causes echo within the space and speech and space to become much more transparent, listening and conversation become more accessible, and music sound becomes better. With the use of the acoustic panel in the room, people become more efficient and relaxed and it works as an important entity in the acoustical interior works.
To reduce the sound entering from the outside through the wall and other types of windows, you need to adopt specific building products and different kinds of construction techniques to block sound transmission.
Interior acoustic inside the room is airborne, and it interacts with the room surface and objects. As we know, sound travels around 344 m/s at room temperature, resulting in multiple reflections with the objects or walls. There are three specific outcomes with sound energy depending on the type of objects they interact with.
Scattering:
Sound waves reflect randomly in a very unordered way as per the object
Reflection:
Any hard surface such as glass, wood and other concrete walls acts as the minor sound wave as it reflects.
Absorption:
Any porous material can absorb the sound, and it propagates into them.
All these mentioned three processes are pretty crucial while creating acoustic for the room. Acoustic level inside the space can only be achieved by affecting the sound wave or any object.
Reverberation time is the typical measurement in acoustical interior works:
It is time that sound takes to subside from its original sound level. It is the parameter of the measurement of the echo of the sound. The absorption area is the perfect sound absorber inside the room, and it is commonly measured in the square meters of Sabine. However, some other acoustic measures are being used while designing an acoustic room like STI (speed transmission index), C50 or C80 (for clarity) and G (Room strength)
There is some myth and truth towards the noising and echoing are listed below.\
- It is controlled by just installing the carpet, but it is not correct that carpet is the sole remedy for acoustic issues. Carpet is the remedy for reducing the noise from the movement of footfalls and furniture movement sound and it can be used as acoustical interior works for a while.
- The second myth is ceiling is enough to overcome sound, but the truth is acoustical tiles are enough to absorb sound. There are many other absorption characteristics of tiles like wood fibre, mineral fibre, glass and other fibre. To make sure effective, one should match the acoustic tiles with the problem. Poorly selected acoustic material can result in more complex and louder noise and destroy the final purpose.
The energy of sound is being taken in the trapped in the material rather than bouncing off or reflected. All the acoustic materials are rated in terms of their ability to absorb noise and sound. So, acoustic panel and other kind of materials are widely used in the acoustical interior works to overcome outside sound as well as inner sound.
