It will assist you in understanding my CRP.
As shown by my Graphic Organiser, there are quite a number of series of events that can lead to hearing loss. You could be at a night club, so close to the speakers that you pass temporal threshold shift and end up having a constant ring in your ears or, your ears end up ringing after every loud sound, even if it is just the TV on '10' volume! This can lead to you getting annoyed as result of the constant ringing. The same effects could occur if you were working in a factory, or just even hearing a constant noise everyday! The annoyance can also, as seen on the Effects page, lead to insomnia (trouble sleeping), psychological effects and even muscle tension and unease as a result of an effect of cardiovascular issues. The ultimate consequence, (as everyone knows), is hearing loss. Even then, hearing loss can be an immediate effect that even causes the tinnitus (ringing of the ears) in the first place! The effects of noise pollution is different for everyone.
