Everyday usability 20 acoustic

Acoustic is an important factor for ergonomic design of workplaces. This maybe forgotten sometimes but it came to my knowledge with my new desk and laptop. The laptop ventilator makes noise in a frequency that interacts with that of the desk. The desk worked as sound box. Whenever I put the laptop on the desk there is a small noise noticeable, just above the hearing threshold level. First I did not recognize it as it was more sub-concisiously. After working a while it began to be very disturbing. To be sure that is a noise and no imagination I asked my friend for proof.
Now are fabrics between laptop and table this helped to avoid the noise.

Here you can read an article with more information about low frequency noise.
