Acoustic Treatment Fundamentals- Types of acoustic treatment and usage

There is a major difference between soundproofing and acoustic treatment. Acoustic treatment strives to make a room ideal for the advantage of the given application, rather than protecting the sound from escaping or if you are confused how is sound measured.

In this post, we will discuss what the choices available to accomplish this are:

Size, Area and shape of the room

Room area has a substantial effect on what you hear in the room. Sound waves may bounce through the walls and add on the direct sound, thereby causing flutter reverberations, early reflections and echo. The bigger the room, the bigger are the impacts. How much we want to add to the direct sound truly depends on the application. Is it going to be a classical music or a concert hall? Are we recording instruments here so that they can be ideal for studio work? These implementations have different kinds of demands and need the ideal type of acoustic treatment. It is apparent that acoustic treatment is both a science and an art. Sound waves also come with different kinds of wavelengths. This is not good for important listening as it artificially enhances the amplitude of the frequency associated. Listening becomes awful and recorded instruments become coloured. This phenomenon impacts surfaces along the height, width and length off the room. Moreover, sound can bounce off the walls multiple times, leading to more complicated resonances like oblique and tangential modes. This is a vast subject; hence we can leave it for future posts on iPhone decibel meter. Most of us don’t have specialized software to handle this, hence this are some beneficial values called bolt ratios which assist us while designing room dimensions.

Keep in mind that these values can be utilized whenever you look for how to measure decibels in any order regardless of the height, width or length. However, these ratios are not the ultimate regarding ideal room ratios and relative acoustic treatments should be. They just provide you a guideline based on what is noticed to have worked over the years in real time situations. Parallel walls may also cause standing waves, hence in professional recording studios, it will be best to keep up the walls at a specific angle to lessen this phenomenon.

Putting all the tools together

The level of intricacy in reverb acoustic panelling mainly depends on the implementation and the budget. For a vital listening ambiance, echo time should be calculated and the accurate absorbers should be utilized to address different kinds of rooms. This may be hard and need technical proficiency and also experience, as sometimes the real time outcomes don’t match the numbers. One mistake that is noticed frequently is the placement of bass traps and acoustic panels. While several foam absorption panels are utilized, the bass frequency becomes louder and makes it harder to address response of uneven frequency.
