REFLEX CALIBRATION STANDARDS AND SPECTRAL PROPERTIES
General Specifications for stimulus and audiometer signals are made to follow
IEC 60645-5/ANSI S3.39.
Ipsilateral Earphone:
Pure Tone:
MAICO Standard Values
Contralateral
Earphone:
Pure Tone:
ISO 389-2 for IP 30
RadioEar Standard Values for DD45 C
Ipsilateral Earphone:
Broad-band
noise (BBN):
MAICO Standard Values
Contralateral
Earphone:
Broad-band
noise (BBN):
RadioEar Standard Values
Ipsi- and
Contralateral
Earphone:
Spectral
Properties
As “Broad-band noise” specified in IEC 60645-5,
but with 500 Hz as lower cut-off frequency.
General
about levels:
The actual sound pressure level at the
eardrum will depend on the volume of the ear.
The risk of artifacts at higher stimulus levels in reflex measurements are minor and
will not activate the reflex detection system.
