I’m really needing new headphones to drown out the noise when I’m out on Public transit or just at home during panic attacks.
Very small requirements for anybody that has some they enjoy.
Bluetooth and works with android devices (preferably without a app aka natively). Has good noise cancelling and can block out most sounds but doesn’t have horrible ringing in them (I’m using from the super cheap kinda noise cancelling?) doesn’t have to be good with music but preferred though.
In ear or over idc about that
Has to be under 100.
If anybody has recommendations it would be awesome.
Fyi new to Lemmy so forgive me if I don’t do some proper “etiquette”. Also autism :p
That’s the theory, but it’s almost impossible to do in practice. Your microphone and speaker are imperfect at capturing and reproducing sounds. The phase timing is incredibly sensitive. You only have milliseconds to do the processing and generation.
That’s why practical noise cancelling relies on feedback loops. A second microphone inside captures the result of the cancellation, and based on that adjustments can be made to the negative signal. This allows you to correct for lots of sources of error and achieve quite a good result. Of course, for a sudden noise like a gunshot, by the time the feedback loop can really kick in, the noise is already over.
Oooooh that makes so much sense, I had been wondering why lifting the earcup slightly doesn’t amplify the sound, but that explains it. Thank you for the clarification!
