That means the sin function completes one cycle when its entire argument goes from 0 to 2π. ω represents the frequency of a sine wave when we write it this way: sin (ωt). If ω=1 the sin completes one cycle in 2π seconds. If ω=2π the sin completes one cycle sooner, every 1 second.

NettetPure-tone audiometry. Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125 kHz to 8 kHz with the use of headphones.
