Hello Stu
Welcome to the thread! Good to have you here.
It’s been a while since I last posted and I can now present more results after a period of experimentation with the Starkeys and how I have improved sound quality (as I perceive it) with some tuning of frequency response ranges.
As you may have found in other parts of the forum, there’s an awful lot of subjectivity in HA discussions because people’s ears and brains process sound in individual ways. Firstly, I had to wear the Starkeys for some weeks before by brain started to “burn in” with the new sound. Clearly, with my hearing loss, my brain appeared to have forgotten what a full frequency response was like. With music I only had a memory of what a particular sound track “should” sound like e.g warm mid-range, a clear sheen of a cymbal sound, the depth of the recording venue and so on.
So I’ve had to put some work in to test the Starkeys in various situations, noisy restaurants, live music venues, HiFi listening, opera with a full orchestra (very wide dynamic sound range).
For voice and general personal listening work, the Starkeys have been very effective indeed and recently I’ve been able to improve frequency response with the help of my audiologist.
Here are the results to date:
Voice modes
Voice in noisy surroundings:
I nearly always use Edge mode but a table mic might improve things - and you can get these. Edge mode does not get rid of louder transients and strong local voices in neighbouring tables in restaurants or pubs. I find myself concentrating on people’s mouths a lot in order to capture speech well. If the ambient noise is lower and a bit more distant, I have no problem.
On the other hand, I probably need to experiment more with the “Enhance Speech” or Reduce Noise” functions more. Currently, I’m using mainly “Best Sound” mode so I doubt that I’m getting the best from the HAs right now.
Restaurant mode is not particularly effective but it is directional - i.e. focused on what the head (and HAs ) are pointing toward. So I need to do more tests with this mode.
Roaming in the hills with wind noise
Edge mode is best for this but it’s not perfect when the wind is strong.
To improve this, my audiologist programmed an “outdoor mode” for me. This increased wind noise reduction so I hope to get some results about this change soon.
Music mode
Music at concerts
Excellent dynamic range and even at a measured 95dB in front of speakers, the Starkeys had no problem.
Music mode is best at open-air concerts, in-tent concerts, in an opera house and in front of stereo speakers.
The drawback with music mode is that the HAs are a straight amplifier at the frequencies they are optimised for so if there is ambient sound before and after a concert it is accentuated and can be irritating; (example, people rustling sweet packets, occasional speech, any exterior ambient noise at an outdoor concert venue etc)
So I need to deactivate music mode when a concert is over or when I’ve finished listening to music on my stereo system.
Music at home
I wrote this paragraph in my diary about 5 days ago - before I went to see my audiologist.
After many tests it’s clear that I am not yet satisfied listening to music. Given that my brain has had to learn when the HAs are approaching their lower frequency roll-off and when to integrate frequencies that are coming through the ear buds directly to the eardrum, I still experience a lack of warmth and depth in a lot of music (piano mid-range for example). High frequency ranges are too sharp. So, I’m not enjoying listening as much as I used to. Some more tuning up of frequency response may be useful but this would be better saved as an alternative programme on the iphone for future A-B testing.
I rely a lot on what my memory tells me about sound tracks I have listened to and, in particular, those I have used for testing HiFi equipment and speakers.
In my appointment with the audiologist we adjusted the following frequency ranges
3.3-9.4 kHz - reduce this range by a maximum of 2dB
(To reduce the accentuated high frequency response I’m perceiving)
150 - 3kHz - increase minimally 1dB (lower range) approx 2dB for mid-range
(To increase warmth e.g. piano low to mid-range frequencies, violin and similar instruments)
In addition to the above, my audiologist reduced the range 7.5kHz - 9.4kHz for Personal mode.
(To reduce the sharpness in voice sibilants and slight echo from hard walls I perceive in Personal mode)
Results?
Music mode - results not yet recorded. I’ll report on that in a later post
Personal mode - immediate improvement with a reduction in the sharpness of highs. Very good.
The moral of the story so far is that I’ve needed to work at it but I’m seeing real improvements in how the Starkeys are performing.
Other features and findings..
Feedback cancellation
The Starkeys are very good indeed with feedback cancelling! In Music mode I can actually use them inside my Headphones (Focal Bathys) which means I can stream the headphones from the TV sound system as well as my streaming amplifier and iphone. This is a real boon for me.
The sound is good although I’m sometimes aware of the cavity inside the headphones due to the HA amplification.
Losing a Starkey Hearing aid
TWICE, I have lost a hearing aid. In both cases I was leaning into bushes while gardening and the bush branches caught one HA. While I was able to roam around with the ‘Find My Hearing Aid” function and get to within half a meter of the HA, the directionality of the Bluetooth signal was not all that good. (I doubt that the location map would be much help – too wide an area location).
What did help immensely was that I could play the Self-Check tones and get a better hearing person to listen for the sound. That worked and we found the lost HA! As long as I have that sort of help, I’ll find the HA. I did not fully test using the one good ear to listen for the test tone but the difficulty would be in location since the sound is being picked up by one ear only.
I may ask the Starkey product people if they could add a function that sounds a warning when an HA is lost i.e. when the Bluetooth signal suddenly becomes very low. That would allow me to know immediately when I’ve lost an HA and would give me time to react before I move too far away to be able to see it.
Summary
The Starkeys have shown that they have great flexibility and that they can filter noise well. So far I’m satisfied with progress. Given that I’ve been an audiophile with some sound studio and broadcast experience in the past I’m surprised that things are going this well. On the other hand I’ve needed to work with my audiologist and be very picky about which frequency ranges are boosted or attenuated.
