parking sensors

[Baz]

on my 2007 crv ictdi 2.2 ex when i press the switch to activate the  parking sensors the sound omitted is quite loud but as i approach an obstacle i can hardly hear a sound only very faint and i mean faint i dont normaly use them but caught the switch the other day reversing into my driveway to park in my back garden i have to pull both the Mirrors in to get between my semi detached and the neighbours thats how close it is, the sensors all show up on the display i'm sure when i got this vehicle just over 12 months ago the sound omitted was very loud. can anyone throw any light on this problem?

I have heard of this issue before but without searching this site for the solution I cannot remember what the problem with the buzzer.
