Abstract

A new multichannel acoustic method for testing large-size concrete building constructions is considered. The method is based on the use of a method of free vibrations (the resonance and impactecho methods) with the subsequent multiplication of partial spectral characteristics. The multichannel multiplicative method allows performance of acoustic testing of large-size compact concrete building constructions (blocks, beams, columns, supports, and other standard articles).
