Available in entire frequency range within the transducer specified range (for SF 125 - 12500 Hz). Accuracy 0.3% Available for each stimulus frequency. 125 to 12500 Hz at standard frequencies Stimulus types Tone audiometry Loudness Scaling Tone, Warble, Pulsed tone, Pulsed warble, FRESH Noise Warble, ISTS, FRESH Noise Narrow Band Noise (correlated) Speech Weighted Noise (correlated) White Noise (Wide band noise) (correlated) Stimulus modulation FM (Warble): SISI: Adjustable modulation rate and depth Modulation rate: 1-20 Hz (default: 5 Hz). Modulation depth: 1-25% of center frequency (default: 5%). 5, 2, 1 dB increments Signal presentation Accuracy of sound level Entire level range (AC): Entire level range (BC): Attenuator 1 or 5 dB step resolution over the entire range. HL Range The maximum output levels from AURICAL Aud depend on the actual sensitivity of the individual transducers, and they will be slightly different for each unit. However, the minimum requirements from IEC and ANSI standards are fulfilled for all units. Total harmonic distortion Air < 2.5% Bone < 5% TDH 39, ME-70, HOLMCO, HDA 200/HDA 300 headphones, and Insert Earphones Bone oscillator (Mastoid) Passive sound field speaker using the built-in amplifier, or External amplifier using the line output. Transducer options depend on how AURICAL Aud is ordered and calibrated.
