The acoustic treatment is the most neglected or misunderstood part of a studio. It is a special touch that makes the room sound good. Professionals spend thousands improving the acoustic of their studio where they record.
The acoustic treatment is a technique that helps in improving the acoustics of the room for recording or mixing music. The main goal behind this process is to make your environment sound more pleasing and neutral with controlled ambiance and get a quality recording.
The acoustic treatment is done by installing absorption or diffusion devices in areas where problematic reflection occurs.
Sadly, there are no size fit solutions available for acoustic treatment. You can use the following acoustic treatment:
• Bass Traps – for low frequencies.
• Diffusers – for delayed reflections.
• Acoustic panels – for broadband absorption.
What are Bass Traps?
They are acoustic absorbers made to prevent the reflections from low-level frequencies. This type of acoustic treatment requires mass and absorptive properties to manage the low frequencies.
To be effective at low frequencies, Baa traps should be properly covered with absorptive material. Bass will disappear from the critical areas and build on others.
What are diffusers?
Acoustic diffusers are one type of acoustic treatment that disperse reflections instead of absorbing them. They are a crucial part of acoustic treatment. If you only install absorbers, the room will sound unnaturally dead. Diffusion allows us to control the reflections without eliminating them completely.
Diffusers best works for handling late reflections at points back from the listening position.
What are the acoustic panels?
These panels work as absorbing devices that work for a broad range frequency of sound energy. The most problematic area is the first reflection point. This is an important area to use acoustic absorption panels. Every room has a different build, design, but the first reflection points are located on the walls to the left and right of the listening position. These panels are made of a rectangular frame filled up with absorbent material and then installed on walls.
Acoustic absorbers are built from material that stops the sound energy from bouncing off hard surfaces like ceiling and walls.
Types of Acoustic Materials used are: –
• Sound Absorbers
Sound reflections create echoes and hinder speech which can turn any environment unpleasant.
• Sound Diffusers
They are used to reduce the intensity of sound by dispersing the sound waves in multiple directions over a large area. Diffusers come in various types- Max. Length sequence diffuser, Quadratic-residue diffuser, Primitive-root diffuser, and Optimized diffuser.
• Noise Barriers
These are the materials that completely cut-down the transmission of sound. The materials used to block sounds are bricks, steel, insulating wool, plastic, concrete, etc.
• Sound Reflectors
These are acoustic materials used to concentrate and reflect waves of sound. This helps in amplifying sounds without using artificial amplifiers. This is usually avoided in smaller spaces. Gypsum boards, fabric-finishes, vinyl are used as reflective materials.
