Figure 6.2.4—Leveling the sound field speaker
1. Follow the instructions found in Sections 6.2.1 and 6.2.2 to position the
client, sound field speaker, and microphones for testing. Only the larger
reference microphone is used for leveling. However, to speed things up and
ensure the client is in the same position for leveling as he is for measuring,
it is recommended that you insert the probe microphone tube in the client’s
ear (described in Section 6.2.3) before the leveling process.
2. Press [F2] from the Opening screen to enter the Real-Ear Navigation screen.
3. Press [F3] or [F4] from the Real-Ear Navigation screen to enter either the
Insertion Gain screen, or the SPL screen, respectively.
4. Press [LEVEL].
5. The instrument will attempt to level the sound field speaker. There are three
leveling statuses:
a. LEVELED—This indicates the leveling process was correct within 1 dB.
b. LEVEL-FAILED—This indicates that the leveling process is incorrect by at
least 6 dB.
c. SEMI-LEVELED—This indicates that the leveling process was correct
between 1 dB and 2 dB.
d. WEAK-LEVELED—This indicates that the leveling process was correct
between 1 dB and 2 dB, but that the maximum output that the speaker
can produce is less than 80 dB SPL. To produce a louder signal, move the
speaker closer to the patient and re-level.
