Watch the video for a brief summary of the reasons why it is important to calibrate the audio system, taking into account the fundamental aspects of environmental acoustics.
When you listen to music from your sound system, technically you are not only hearing the sounds coming from it, but a mix of sounds coming from the speakers and the noises of the environment.
Part of the waves coming out of the speakers go directly to the ears; a part bounces off the walls on the ceiling or floor; a part is absorbed; some of it is reflected and only then reaches our ears.
These phenomena of absorption or reflection distort the listening experience and, depending on the size of the room and of the absorbent or reflective materials, there are important differences when listening to the audio system.
To correctly calibrate the audio system, it is necessary to start from an acoustically correct room.
