Because of the excellent sound isolation the interior acoustics were "challenging". In particular the room had a number of audible and measurable bass issues due the stiff walls. To provide high frequency damping thin drapes had been added in many locations.

The chart below shows the reverberation time before and after treatment. It is clear that the removal of the thin drapes and its replacement with proper acoustic treatment helped to restore a more balanced high frequency decay profile.

"Music Lovers has been a leader in high-end audio and video sales and service for over 20 years. In our business it is crucial for us to have great sounding rooms. Before Nyal from Acoustic Frontiers' recommended changes for acoustic room treatments were implemented, our room had several issues across a wide range of frequencies and often overloaded. Once his solution was in place, our room has never sounded better and is now able to achieve a level of clarity, focus and depth that was previously unattainable. In addition to being extremely thorough, Nyal was very easy to work with and continued to provide us with support and recommendations on how to further improve our room. We have since recommended Nyal and Acoustic Frontiers to many of our clients who are in need of room measurements and/or treatment solutions." Josh, Store Manager, Music Lovers Audio.
