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 to be confused with the rayleigh unit of photon flux, which is used to measure airglow and is named after his son, Robert John Strutt, 4th Baron Rayleigh. (Wikipedia).
