6. TECHNICAL DATA
6:1 Attenuation values, SNR (D)
The attenuation values and noise levels for the headset are tested and
approved according to EN 352-4: 2001, EN 352-6 : 2002, EN 352-8 2002 and
applicable parts of EN 352-1 2002. Certicate issued by FIOH (registration
no. 0403).
Explanation of the attenuation data tables:
1. Weight
2. Frequency (Hz)
3. Average attenuation (dB)
4. Standard deviation (dB)
5. Expected attenuation (dB)
6:2 Input signal level/usage time for audio input J22 (E)
Maximum permitted audio signal in relation to usage time.
To prevent harmful effects on hearing, the input signal should not exceed the
speciedvalues(averagespeechsoundlevel).Thelong-termaveragevalue
of the earphone volume is measured at a level corresponding to no more than
82 dB(A) sound level.
