I wouldn't expect someone visually impaired to not review a toy because they can't see the color.
Someone who can't hear should be able to review as well. Simply indicating they can't hear, or asking someone else to do a sound check, or checking other reviews to give a rating if they don't want to disclose their impaired status publicly would all be fine from me... honestly, I'm more annoyed with guys reviewing female-marketed toys and then not disclosing that oh yeah, they were using it anally. I read a review blog once and it wasn't until a few reviews in that at one point the poster indicated he was using vibrators on his cock... wouldn't have bugged me if he'd indicated he was using them on different equipment right off.
But for someone who can't hear? The important part is the vibration and toy quality. Yes, sound is very important... for me, I live with kids around and wouldn't get anything louder than two bees for use. But it's not the most important part of the review. Sometimes I have to read more than one review to get an idea how how something will sound... just like I read more than one review to get an idea of how something will feel.
Honesty is key. That's all.
