Oticon more permanent white noise

They should be available for that kind of money. Real 2 is a pretty good option too.

Someone in your region should be able to help: providing you don’t want to have an aftercare package.

I’ll swap you a pair for a RHD S500 R129 in good condition

It does exist for people with normal LF. I’ve got a couple of clients who can hear the noise floor. I can hear it when I’ve demoed aids.

I suspect it’s something to do with the bigger sampling bit-rates of the latest aids combined with the machined silicone mics that appear to be in use. Historically, electret mic noise was down to around 20dB. The biggest issue with silicone wafer mics was that they struggled to get the noise floor below 30dB due Brownian motion impacting the low mass/high sensitivity of the diaphragm.

Looking at the mics in use today, there’s been a workaround implemented. However, it’s possible that the efficacy of the workaround hasn’t been as good as originally expected or the rate of improvement of the sampling/widening of the input band has jumped ahead of the hardware in terms of sensitivity. However it could be the case that the other engineering benefits of these mics outweigh the noise floor issues.

The fact that Oticon do have this (hidden) adjustment in their software indicates to me that they know there’s an issue, but didn’t want to apply a cut in sensitivity across all users.

The riddle is solved!
As i mentioned, if all else fails, i go to the extreme - i try to think
And if this fails too, i read the manual!

Had i read the data sheet for the more series thorough enough, i would have found a clear specification:
Equivalent input noise: Omni: 21db, Dir: 29db (ear-simultor)
So it’s specified, that the more’s have a permanent noise like a breeze or low whisper.

This corresponds to our discussion:
As a result of the sophisticated signal processing we have a noise (microphone, variable preamp (“MoreSound Amp”), conversion, quantisation) of 21db - and as mentioned, the directionality will add another 8db.

There ain’t no free lunch - we’ll have to accept the devices own noise in exchange for its excellent noise reduction.

(Nevertheless i have ordered my more1s today. It costs me a fortune, but its worth it)
(And i will order a NoahLink Wireless too).

A possible upside of the floor noise is that it can sometimes help with tinnitus.

Update:
The noise is actually coming from the microphones (and the PreAmps).
When i find the time to watch (=stream) a complete feature of 90min on tv, afterwards the waterfall rushes back into my ears. The streamed film sound lacks the floor noise, but contains all the ambient sounds, so for a while i forgot how to fade it out.
Btw: although streamed sound has no “directionality”, the MoreSound Booster works nevertheless.

I don’t seem to notice it at all with my resounds…

That’s quite possible. It is easy to construct a “squelch” that silences the output, if it is below a certain level. The drawback is, that it cannot distinguish between noise and a low sound that you may want to hear (e.g. the rustling of a person coming up behind you).
This is a question of the manufacturers philosophy - oticon tries to show you everything - at the cost that you have to select yourself what is relevant.

I have 2 Oticon Real 1 hearing aids (both for my left ear) one has the “60” receiver and the other one the “85”. They are programmed to give the same amplification however the one with the 85 receiver has much more floor noise. Is this normal?

Ok, good to know interesting that the noise floor issue fix might be resolved by the 60dB receiver.

I’m going to try that out with a a client I have who has persistent tinnitus and a HF loss like yours with a negligible low frequency loss. It sounds like there’s a fix implemented in Genie to deal with the noise floor generated by mic noise for the 60dB recs which makes sense.

Previously we haven’t made much use of the lowest power receivers as they haven’t offered much over the next size up, but I can see this is a definite application.

I’ve been following this discussion - I have just gotten new Intent 2 hearing aids and the background hiss has been driving me CRAZY. My audiologist tried all kinds of “fixes” to no avail. The noise was not always there - and when it was, it cut in and out. When it was there MAY have been related to wheather the HAs had disconnected from my I-Phone XR - not sure - but I just stumbled across a much earlier post about a muck earlier HA (Oticon Play) with the same problem, and it referenced “background sounds” - and a setting that can be reached by clicking the top right side button in the i-phone 3 times with commander open. When I did that, balanced noise was clicked with volume at about 9. Going to background sound settings at the bottom of the screen there is a setting “stop sounds when locked” that was also enabled. I disabled the stop sound when locked and tried playing with sound levels - and it was still there. I switched to “rain” sound and set it to zero - and TOTAL SILENCE!!! No more hiss!!
Then I went back to balanced noise at zero and it was still quiet - before switching to “RAIN” setting to zero on balanced, bright, or dark did not totally eliminate the noise - and dark was less objectionable than bright or balanced. Now whichever sound I select and set to zero, it is quiet.
I find this inconsistency strange, but not as strange as how difficult it was to get to this point. I will continue to monitor, but I am more confident in these hearing aids NOW than I have been for the last 6 weeks!!!

my aids are very quiet when I am in a very quiet environment. I believe your audiologist should return your aids or replace them.

The hearing aids keep dropping the blue-tooth and when it drops it turns the background sound feature off - and it doesn’t come back on when blue-tooth restarted. I have to turn it back on with the control panel on the phone. I will be talking to the audiologist this afternoon.

@CLSnyder I’d be interested to hear what the audiologist has to say. There are connectivity issues with Oticons, surely with my Real1. I thought they had overcome this with the Intent, but maybe that’s not the case.

I dripped them off at the Audiologist today. They are sending them to OTICON, said they will likely be replaced in a week to 10 days. In the meantime I am back with my OPN1 set that is going through batteries in 2 or 3 days. They are 8 years old and other than the 4x8 beep issue and increasing appetite for batteries they have been FAULTESS. I was (naively?) hoping for the same with the Intents.

@CLSnyder Be of good hope. I’ve read a lot of very good reports about the Intent series. The fact that they are sending them to the manufacturer is a positive sign.
