Whilst I have no idea how well this would work, I would definitely appreciate something like this.

Rather than noise cancelling headphones, I’d be happy with an audio recording that has my loss applied to it. Anything to demonstrate what it’s like would help awareness and understanding.

Email your audiologist and ask for your audiogram. Should be straightforward to apply an equalizer to match it, esp if can find an equalizer with db(a? m?) labels
