Anechoic chamber near me
Orfield Labrotories in Minnesota have built an anechoic chamber that is so quiet that no-one can bear to be inside for more than 45 minutes. It has entered into the Guiness Book Of World Records as officially the quietest place on earth – tests measured background noise in the chamber as -9.4 dBA. Yes, that’s minus 9.4 decibels!In general, a pyramidal model can be an ideal absorber for anechoic applications because it provides good absorption performance for near normal and normal incidence angles. The results of the design and testing of the wedges model for anechoic are expected to be references in designing the optimal anechoic chamber room.
