Firstly, l have created a post about changing the sound setting via software and the separate volume adjustment on each aids for Phonak P70 Up Nadia. Thanks to those community people who answered my questions.
I have app on my phone and audiologist modified the sound features such as noiseblock and others.
It seems fairly ok but need to go back again after christmas time.
Meanwhile, l wonder if anyone have the similar issue that it sounds like digging machine, it is much like a concrete road breaker machine. It happens when it’s loud sound and slightly long pause in various decibel/frequency - Microwave, boiling water( kettle), toilet flush and few words like ‘errrr’, ‘ooooh’, ‘aiiiirr’, I noticed the annoying sound of ‘digging machine’ after one day.
I think it is something to do with a combination of frequency and decibel in advanced setting via computer in hospital. Or maybe on my app that l increased/decreased the level of volume, dynamic and noise in personalised program setting.
