Akomo and room acoustics
What are good or bad room acoustics
It is taken for granted that a concert hall or recording studio has been optimised for the function in question. Right from the start of the design phase, these types of rooms have been carefully engineered to create the optimal acoustics for their given purpose. From the start a lot of thought and research has been put into choosing the right materials and configuration.
In contrast to the concert halls and studio’s, a lot less thought is put into the importance of acoustic comfort in offices, hotels, restaurants, meeting rooms and in fact all areas where people meet and come together.
Apart from the mandatory regulations there is often little thought given to acoustics.
The problems become apparent when the room is in use. Think of a restaurant where people need to speak louder to be heard. This will add to the problem and lead to further increases in the noise level.
The cause of poor acoustics is, more often than not, sound waves being reflected around the room with the sound remaining audible longer than normal.
This reflection of sound waves is called reverberation.
Longer reverberation times cause poor speech intelligibility and lead to an increase in the sound level (noise).
Reverberation time can be measured and is indicated in seconds.
A room with long reverberation times can lead to stress and tiredness but, in the most cases it is first noticed as an uncomfortable, sometimes annoying, place to meet.
