6. PARAMETER DEFINITIONS
Dynamic Range (DYR)
Total Harmonic Distortion + Noise (THD+N)
The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
bandwidth, typically 20 Hz to 20 kHz. Dynamic Range is a signal-to-noise ratio measurement over the spec-
ified band width made with a -60 dBFS signal; then, 60 dB is added to the resulting measurement to refer
the measurement to full-scale. This technique ensures that the distortion components are below the noise
level and do not effect the measurement. This measurement technique has been accepted by the Audio
Engineering Society, AES17-1991, and the Electronic Industries Association of Japan, EIAJ CP-307. Ex-
pressed in decibels.
The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
band width (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels. Measured
at -1 and -20 dBFS as suggested in AES17-1991 Annex A.
