Early reflections (ER) are an acoustic problem that’s especially relevant in the control room. Because they take a “detour” via the side or rear walls, these reflections reach the ears with a slight delay. When early reflections contain a lot of energy and the distance is large enough, they are clearly perceptible as echos. Read more

In addition to special, resonant designs, acoustic room treatment relies heavily on so-called porous absorbers. These are open-pored or open-celled structures which let air pass through, but apply some resistance. This friction converts sonic energy into heat energy and slows down the movement of the air. This is what we call absorption. Materials used include PU foams, melamine resin foams and mineral wool. They all have the same working principle, but quite different sonic characteristics.

For the most part, the speakers used in music production are different from the ones used for pleasure listening. Studio monitors have certain characteristics that differ from their hi-fi counterparts. Read more

You probably know the staggered series of echoes that occur when you clap your hands in a small, empty room. That’s an example of flutter echoes. Flutter echoes are staccato-like repetitions which stand out of the diffuse reverberation and are clearly perceptible. Read more
