New sounds or long lost sounds

Everyone's hearing will decrease gradually as they get older, and we are often unaware that we have lost the ability to hear certain sounds, or the fact that we have gradually got used to hearing sounds differently (sounds that we accept as being normal, as we know no different). For instance hearing the fridge humming, floors creaking, taps running and footsteps on a hard floor are common sounds that are easily forgotten. With hearing aids in, these sounds can seem very new and in some cases quite intrusive until you become accustomed to them. This is quite a normal experience, over time, you will learn to 'tune out' the sounds that are not important and become gradually accustomed to the different types of sound.
