FAQ (cont.)
Q: How do the hearing aid microphones behave during a streaming session?
A: • During a Fitting Session, each hearing aid memory is set up to be Omni, Directional, or
Dynamic Directional (default). For example, memory 1 is set to Dynamic Directionality.
• If streaming is enabled in memory 1, Dynamic Directionality will still be active meaning
that a hearing aid microphone could switch between Omni and Directional modes during
a streaming session.
• During streaming, microphone behavior should be the same as when not streaming.
Q: During streaming, why does my hearing aid microphone seem to attenuate sound more
than I expect?
A:
• The hearing aid applies environmental adaptive features to BOTH streamed audio and hearing aid
microphone audio. Depending on the type of audio input and settings for hearing aid adaptive
features, higher levels of attenuation for the hearing aid microphone audio are possible. This is
expected and normal.
• If "too much" audio is being attenuated by the hearing aid microphone, we recommend using
Inspire to create a "dedicated streaming memory" and make the following adjustments:
®
» Reduce "Voice iQ" setting to 0 or 1
»
Reduce "Wind" setting to 0 or 1
»
Reduce "Machine Noise" setting to 0 or 1
» Set directional microphone to "OMNI"
» "Quiet" environmental adaptation should not be active during streaming sessions, so it
can be left unchanged
Q: While streaming, what happens to my hearing aids when I turn off the TV or
SurfLink Media?
A:
If the Audio Source or SurfLink Media are turned off (streaming connection lost), the hearing aids
will no longer be streaming, but they will still be in "streaming mode." Whenever the streaming
restarts (e.g., TV or SurfLink Media turned on), then hearing aids will restart streaming without
patient intervention.
Q: What happens during a telephone call?
A:
SurfLink Media streaming is disabled in telephone memories.
» Example: Patient has streaming enabled in Memories 1, 2, and 3. If patient is streaming
audio in Memory 3, uses the SurfLink Remote to cycle to Memory 4 (which is in rotation),
then streaming would stop. Memory cycling to Memory 1 would restart streaming in both
hearing aids.
Note
While streaming audio, ear-to-ear commands are not possible.
»
Example: Assume patient has set up hearing aid Memory 4 to be autocoil or ATR. If a
telephone call is received during an active streaming session (e.g., Memory 2), then
"phone ear" will enter Memory 4. All streamed audio to "phone ear" will stop during
telephone call. "Non-phone" ear (still in Memory 2) will continue streaming at same audio
level. After telephone call ends, "phone ear" hearing aid returns to Memory 2 and audio will
restart streaming.
Q: Why does streaming audio sound different when compared to Wireless Headphones?
A:
• The electronics used inside the SurfLink Media are optimized for speech transmission, rather than
full-fidelity music transmission. As a result, the SurfLink Media primarily transmits frequencies that
are below 4000Hz and samples audio input at rates consistent with speech (which is less often than
musical audio sources), slightly reducing fidelity. It is not a flaw, but rather a design decision to
prioritize speech recognition.
• Think of the SurfLink Media as a TV/Speech streamer, not as a Hi-Fidelity Music streamer. It will
sound different than High-Fidelity headphones, and this is by design. If the patient has their
hearing aid microphone on during streaming, any sounds gathered directly from the environment
(via hearing aid microphone) should sound the same. If attenuation is enabled, it may get applied
during active streaming sessions.
Q: My Plantronics CS50 wireless telephone headset seems to interfere with my Starkey
Hearing Technologies wireless products. What should I do?
A:
• The most common interferer for Starkey Hearing Technologies wireless products is the Plantronics
CS50, a wireless headset that operates at 900 MHz. The best solution is to eliminate the CS50 and
replace it with a CS55 unit.
• The Plantronics CS55, CS70, and Savi series headsets use a different band (1.9GHz) that does not
interfere with Starkey Hearing Technologies wireless products.
Q: Can a Professional program and stream audio to the same set of hearing aids at
the same time?
A:
At present time, we do not support concurrent streaming and programming.
