I suffer from Hypersensitive hearing to low decibel sounds. I can clearly hear a phone ring inside whilst outside etc. I don't care about the noise level itself and can easily block out normal to high decibel sounds like normal talk (and full on storms etc), but what actually agitates me and disallows me to concentrate on my task at hand is whispering. I understand that sometimes things need to be briefly whispered but if a conversation is longer than a couple of sentences I easily get frustrated and distracted. My work allows me to wear headphones which I do on a regular basis and specifically moved to a less populated part of the office as I don't expect to disrupt everyone but a lady choose to move next to me 6 months ago and frequently has extended whispered conversations daily. I have advised my manager about this and nothing has been said to the person. I am an upfront person and would like to just advise them of the same above and ask them if they could either move the conversations to another location should they not wish to be overheard or actually speak in a normal quiet voice instead of whispering. Do you think it is acceptable for me to approach the person directly seen as management haven't and what I ask is not an unacceptable request?
