Most indoor rooms and halls have loads of reflective surfaces and as a result you get lots of noises, and reflections of the sound waves. The acoustic solutions for different room may vary but they are based on the same principles. Apart from the physical size and structure of the room, one has to pay attention to the home theater acoustic treatment of the room right from the start. It is seen that people delay the acoustic to a later stage. They do manage to improve the sound proofing and reduce noise, but they can never expect perfect solutions. It is essential for the architecture engineers and acoustical expires to work together when the room is being laid. This will not only help you get the best results but also save on time, costs and efforts. |
Get a complete off-site analysis of the acoustics of the room and the hall. Given below are some important aspects to look into for soundproofing and acoustic solutions.
Dimensions of the room Calculate the complete space of the room in cubic volume. This is essential if you want to find the existing sound absorption and come to some conclusion about the desired acoustical result. The length, width, height of the room as well as the sides and the ceiling too should be taken into consideration here.
Look at the surfaces See what the walls, floors and ceilings are going to made of. Different rooms will of course use different materials such as carpet, masonry, tiles, wood, marble, etc. These surfaces will carry unique properties and impact the acoustical environment in the room in a different way. One has to discuss on what kind of acoustic panels and acoustical foam need to be used in the room to get the best sound proofing. If the existing wall has some sound absorptive value, then a new layer of acoustical material may offer only a nominal difference in absorption.
The seating arrangement The acoustics in a room also get impacted by the attendance of the room and the sitting arrangement. The acoustics will vary with season and attendance. For example, in winters, a complete full hall with people wearing heavy winter coats will reduce echo. But the same audience will make for a less absorption during summers.
Current issues and complaints are often about lifelessness in the sound and intelligibility. It is a good idea to rope in non-technical listeners to offer input for acoustics. Sometimes people working with regular sound for years are not able to give a good advice. it is the use of the right designing and good quality acoustical panels that will make all the difference. No cookie cutter approach is going to work here. Every room and its space are different and needs different treatments.
