Do you have severe echos within your environment? Are people complaining because they can’t hear due to audio reverb or ambient noise? Acoustical engineering can evaluate the area to see what is necessary to improve these scenarios.
This can be done by first seeing what is the issue causing interference. Adding Acoustical Paneling and using Audio Programs to equalize the system are just a few ways of re-engineering the area. HVAC systems can cause the lowest of ambient sound not typically heard until a microphone picks up this noise and amplifies it thru the system. Now the environment has a disturbing effect. With the correct materials absorbing noises like this the audio system will produce a clearer sound to make a more professional appearance.
