2.8 Leveling
Leveling is the process by which the response of the sound chamber or sound
field is measured and computer-corrected so that a flat sound field is achieved.
Sound chamber leveling can be saved into permanent memory, but sound field
leveling for real-ear measurements must be done for every patient and every ear.
See Section 3.2.1 and Section 6.2.4 for instructions on how to perform coupler
and real-ear leveling, respectively.
Here are some technical details on the leveling status messages.
• UNLEVELED: Leveling has not been attempted and sound is uncorrected.
• LEVEL_ERROR or LEVEL_FAILED: An error happened during leveling
and source is uncorrected.
• LEVELED: Leveling has been achieved within ± 0.25 dB between 260–
6000 Hz and ± 0.5 outside that frequency range for sound chamber level-
ing or within ± 1 dB between 260–6000 Hz and ± 2 dB outside that fre-
quency range for real-ear leveling.
• SEMI_LEVELED: Leveling has been achieved between ± 0.25 dB and ±
0.5 dB between 260–6000 Hz and between ± 0.5 and ± 1.5 dB outside
that frequency range for sound chamber leveling or between ± 1 dB and
± 2 dB between 260–6000 Hz and between ± 2 dB and ± 6 dB outside
that frequency range for real-ear leveling.
