Example:
The following measurements were made on a headphone
D T 1 5 0 B E Y E R of i m p e d a n c e 2 5 0 Ohms.
The level in dBu is that recorded on a sinusoidal signal
from 1000 Hz to the headphone terminals at the limit of
the saturation.
The level in dB SPL is raised with a B & K sound level meter
2260 able LAeq and in pink noise analysis at of saturation.
The sensor capsule of the sound meter placed 2 cm from
the transducer and the headphones open.
For other helmets, take the same measurement and set the
switches to limit the power in dB SPL at the desired level.
AMC625 is always delivered in corresponding position 1
in the OFF position of the limiter.
