Musescore versus other sounds
Dear specialists,
I have a cochlear implant and I am doing rehabilitation which is kind of learning the sounds. I have one ear at normal condition. I have founs strange behaviour, that sounds created at different sources are very different in cochlear implant recognition.
By using athe link
https://ln5.sync.com/dl/ef191bed0/xd5j6zgd-35i5uumh-5sxqeqab-pw6isf78
one can load three groups of sounds: Musescore piano, musescore bassoon and TeamHearing piano. The last one is definitely different in recognition in cochlear implant wile all three can be easily recognised by normal hearing.
My question is: what in you opinion, make a difference between Team Hearing and Musesciore?
Regards
Krzysztof

I think we need to know what teamhearing is. I can't tell from your paper or the websites I looked at. How are sounds delivered to your implant?

There are two ways of delivering sound to the cochlear implant: acoustically (normal) or by induction loop. In both cases the effects are the same.

Okay, I see: bassoon Musescore, piano Mmusescore, but nothing that says "TeamHearing piano" - unless the .mp4 is the TeamHearing file.
If that's the case, then comparing uncompressed (lossless) .wav files to compressed (lossy) .mp3 files is not a valid comparison. The differences in the two file types may have a more pronounced effect on your cochlear implant than it does to your other ear.
A better test would be to compare .wav to .wav, or .mp3 to .mp3.
...all three can be easily recognised by normal hearing.
The mp3 file format was created to shrink file size by removing parts of the sound that have the least effect on perceived quality. It exploits psychoacoustics - i.e., how sound is "normally" perceived. Your implant may be more affected by this compared to your normal ear.
Regarding file comparisons (of the same file format):
For example, to compare a MuseScore wav file to a TeamHearing wav file of a piano (playing the exact same notes), one could use an audio editor like Audacity to check the spectrum analysis. Differences will be apparent.

The cochlear implat is designed as a tool which help to recognise the speech and other sounds. The diffrerent formats is rather technical issue related to data storage and coding. I hope that trained listeners may characterize the differences.
Is it true that musescore sounds have some effect related to a hall size and reverberation? Or may be some other effects?
If yes, can they be quantified?

Thank you Jm6stringer,
I am not specialist. If we have some sounds:

Can we characterise them what effects were included? It is important forus because these sounds were trained for years, so we would like to have their characteristic.
