Whether you are reading a book for a radio show in a sound recording studio, for a movie character, or for the visually impaired, it is very important that the message transmitted while doing voice-overs sounds clear and natural. The main problem in sound recording studios is that the microphone cannot distinguish unwanted sounds. The microphones capture any sound we don't want to be in the recording, such as the sound from the air conditioner, the sound of an outside door. If the room has hard surfaces, the sound is reverberating back and forth between the walls and the window. This makes it difficult to understand the sound.
For example, if the efficient frequency sound insulation in a studio environment is 40dBA, the sounds of 75dbA and above in the studio environment will reach dimensions that will disturb the neighbors and the environment by creating noise pollution. In a musical instrument such as a drum, the sound is always high and dimming cannot be done because there is no volume adjustment.
The sound insulation of the recording room can be provided with different sound insulation materials. It is one of the places where the external sound does not want to be reflected inside in terms of protecting the acoustics in the sound recording rooms. In addition, the provision of acoustics inside is just as important as unwanted sounds outside. Acoustic sponges or panels can be used for acoustic arrangements in the interior.
