<strong>CROS</strong> vs. Bi<strong>CROS</strong><br />
What‟s the difference?<br />
Patient requires just the<br />

other side<br />
<strong>CROS</strong><br />
Patient requires the<br />
transmission of sound to the<br />

Battery drain is affected by:<br />
• Wireless technology<br />
– Our instruments have the capability of streaming full speech signals ear<br />
to ear – this can take a huge toll on battery consumption<br />
– Digital wireless accessory use (eg. iCom, ComPilot)<br />
• Brand of battery<br />
– We recommend Rayovac or powerone<br />
• Size of receiver<br />
– Going from a Standard to power receiver (with the same size battery)<br />
will increase battery drain

<strong>CROS</strong> and Bi<strong>CROS</strong><br />
Once connected, define if <strong>Phonak</strong> <strong>CROS</strong> shall be used as <strong>CROS</strong> or<br />
Bi<strong>CROS</strong> system.<br />
It is important to enter an audiogram for the hearing ear.<br />
• The <strong>CROS</strong> transmitter microphone is not active during the fitting.<br />
• The hearing instrument on the hearing ear can be adjusted in the same<br />
way as in a standard fitting.

and the hearing instrument is adjustable.

Loudness summation – hearing instrument alone is<br />
defaulted to 80% of the target gain for the Bi<strong>CROS</strong>
Therefore….<br />
• If your client chooses to wear the hearing instrument on its own (ie.<br />
transmitter off), they will likely find it is not loud enough<br />
• We can address this use case with a few programming steps
1) Add an additional program<br />
• choose the type of program that is consistent with the<br />
environment the client does not want to wear the transmitter in<br />
(ie. calm situation)<br />
2) Turn the transmitter “off” in that program<br />
• Fitting > Fine tuning > Program options > <strong>CROS</strong> microphone<br />
3) Verify the hearing instrument in that program & adjust gain to target<br />
and listener preferences<br />
• Remember the hearing instrument is 80% of the target gain,<br />
therefore, this program will require a gain increase
Verification of a <strong>CROS</strong> or Bi<strong>CROS</strong> system<br />
Step 1: Verify your hearing instrument fitting<br />
a. Position Verifit reference<br />
mics on both ears<br />
b. Insert probe mic into better<br />
ear only (red arrow)<br />
c. Position both the hearing<br />
instrument and <strong>CROS</strong><br />
transmitter in ears<br />
d. Select & the<br />
relevant hearing device<br />
<br />
e. Activate the hearing<br />
instrument only and verify<br />
in the normal fashion using<br />
speech map
Verification of a <strong>CROS</strong> or Bi<strong>CROS</strong> system<br />
Step 2: Verify the response on the better side<br />
a. Turn the <strong>CROS</strong> transmitter on<br />
b. Keep selected in the<br />
hearing instrument area of the<br />
Verifit<br />
c. Turn clients head by 45 degrees<br />
so that the better ear is facing<br />
the speaker<br />
d. Record the Speech (Std1) at<br />
your preferred dB SPL level<br />
Note: You must be out of the<br />
Target fitting session to<br />
activate the <strong>CROS</strong> transmitter<br />
for this measure.
Verification of a <strong>CROS</strong> or Bi<strong>CROS</strong> system<br />
Step 3: Verify the response on the poorer side<br />
a. Rotate client so that their poorer<br />
ear is now at a 45 degree angle<br />
toward the speaker<br />
b. Select in the hearing<br />
instrument area of the Verifit<br />
c. Record the Speech (Std2) at the<br />
same level used in Step 2.<br />
a. Ideally the „better ear‟ and<br />
„poorer‟ ear responses should<br />
be identical, or in the least<br />
instance quite similar.
