WebMatch words. High-precision PET fabric with a bandwidth from 5 to 3300 Rayl ( MKS) ParaCrawl Corpus. A Rayl, rayl or Rayleigh is one of two units of specific acoustic impedance or, equivalently, characteristic acoustic impedance; one an MKS unit, and the other a CGS unit. These have the same dimensions as momentum per volume. The units are named after John William Strutt, 3rd Baron Rayleigh. They are not … See more Specific acoustic impedance When sound waves pass through any physical substance the pressure of the waves causes the particles of the substance to move. The sound specific impedance is … See more • Dictionary of Physics Units of Measurement • A discussion of the history and ambiguity of the rayl See more flagler beach building forms
