There are a few classic physics problems that it can really help to have a mental map of. One is, of course, wave propagation. From big-wave surfing, through loudspeaker positioning, to quantum mec… ...

According to the filing, ridges in a finger pad introduce an acoustic impedance mismatch that causes the mechanical waves generated by a transducer to reflect or diffract in a known manner.

This report describes a simple method of measuring the specific acoustic impedance of membrane-type bass absorbers, i.e. of absorbers which consist of a vibrating membrane, the mass of which ...

The broadband impedance matching between air and water could promote the applications in water-air acoustic communication.

This work explores compact broadband acoustic absorbers with coherently coupled weak resonances and provides deep insight into the fundamental characteristics of these coupling systems, which may ...
