Ing. Karel Motl

AV Designer / Room Acoustics

Expert on room acoustics

I like to be at the very begining of a design, when we measure, analyze and create the concept of room acoustic itself. The more interesting the task is, the more I like it. The ideal situation is when I can cooperate with an architect and we are able to create a tailor-made conversion. Then we’re not limited by using the prefabricated parts.

If you like building speakers at home, you look for an appropriate place to measure the prototypes. Balcony is ideal for measuring for the reason of the minimalization of the sound reflections. However, neighbors are not that excited about it as you need to use the sounds of whistle and hum for these measurements.
