Acoustical characteristics of a multichannel transmission line

Acoustical characteristics of a multichannel transmission line Abstract The properties of an acoustic system called by the author ”a multichannel transmission line” (MTL) are considered. Analytical expressions are derived for the following main acoustical characteristics of an MTL consisting of an arbitrary number N of single lines: the input impedance, the resonance frequencies, the reflection and transmission factors for an MTL-insulator, and the reflection factor for an MTL-absorber. For these quantities, numerical calculations are performed, and their frequency dependences are presented for different parameters of the constituent lines in the cases N=2 and 3. It is shown that the acoustical characteristics of MTL-insulators and MTL-absorbers have considerable advantages over the characteristics of similar systems designed on the basis of single lines. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

Abstract The properties of an acoustic system called by the author ”a multichannel transmission line” (MTL) are considered. Analytical expressions are derived for the following main acoustical characteristics of an MTL consisting of an arbitrary number N of single lines: the input impedance, the resonance frequencies, the reflection and transmission factors for an MTL-insulator, and the reflection factor for an MTL-absorber. For these quantities, numerical calculations are performed, and their frequency dependences are presented for different parameters of the constituent lines in the cases N=2 and 3. It is shown that the acoustical characteristics of MTL-insulators and MTL-absorbers have considerable advantages over the characteristics of similar systems designed on the basis of single lines.
