1. Audiometer Classifications: Class 3.
2. Air conduction:
(1) Frequency: 250Hz,500Hz,750Hz,1000Hz,1500Hz,2000Hz,3000Hz,4000Hz,6000Hz,8000Hz;
(2) Hearing level≤110Db.
3. Bone Conduction:
(1) Frequency: 250Hz,500Hz,750Hz,1000Hz,1500Hz,2000Hz,3000Hz,4000Hz.
(2) Hearing level≤60dB
4. Minimum hearing level: The minimum hearing level should be -10dB for pure-tone audiometer of Class 1 and Class 3.
5. Frequency accuracy: The allowable error of frequency for this audiometer is ±2%.
6. The accuracy of audiometer controller: Step of the audiometer controller should be ≤5dB; the deviation of the indication difference between two adjacent hearing levels should be ≤3/10 or 1 dB of the step. Adopt the smaller value.
7. Masking Noise Level Range: The masking noise of the audiometer should be able to mask pure tone of at least 60dB at 250Hz, 75dB at 500 Hz, 80dB at 1000Hz~4000Hz. The masking noise level should be adjustable within the range from 0dB to the above level.
8. The accuracy of masking noise level : The allowable error of the masking noise level should be -3dB~+5dB.
9. The accuracy of masking noise level controller: The step of the masking noise level controller should be ≤5dB. The deviation of the indication difference between two adjacent hearing levels should be ≤ 3/10 or 1 dB of the step. Adopt the smaller value.
10. When the unwanted sound radiated by pure tone audiometer is >50dB HL, people with normal hearing should not hear any unwanted sound radiated by the pure tone audiometer.
11. Pre-heating time: from 5 minutes to 10 minutes.
