Rayl
rayl[rāl] (acoustics) A unit of specific acoustical impedance, equal to a sound pressure of 1 dyne per square centimeter divided by a sound particle velocity of 1 centimeter per second. Also known as specific acoustical ohm (Ωs ); unit-area acoustical ohm. Rayl a rarely used unit of specific acoustic impedance in the cgs system of units (see ACOUSTIC IMPEDANCE). It was named in honor of the British physicist Lord Rayleigh. The rayl is the magnitude of a medium’s specific acoustic impedance for which a sound pressure of 1 dyne/cm2 produces a linear velocity of 1 cm/sec in the particles of the medium; 1 rayl = 1 dyne-sec/cm3 = 10 newton-sec/m3. rayl
