OCR: Delay = int DisiFE F = Sampling frequency V = Velocity of sound. (b) Gain = ( Attenuation)" Distreference DistMS Attenuation = Number from 0 to 1 indicating absorption of the wall. N = Reflection order (number of reflections). (c) y(n)'= >Gain(m)(n = Delay(m)) M = Number of sound rays Gain(m) = Array of scale values, Delay(m) = Array of delay times in samples; x(n) = Array of input samples. Figure 6: (a) The delay imposed by a reflection; (b) relative sound level, accounting for distance and sound loss due to reflections; (c) computing the final sound.
