Common symptoms of hearing loss include:

• Sounds seem muffled, or when people are talking it sounds like they’re mumbling. This is because often (especially in age-related hearing loss) the high frequencies (those that make up the consonants) are the first to be affected by sensorineural hearing loss; and it's these that give clarity to speech.

• Trouble hearing and understanding conversation especially in background noise like others talking or having the television or music on. 

• Turning the television or radio to a higher volume than you used to.
