My problem with my H4N is when i start recording,without any sound in the room , the sound pointer become very noisy during recording, so the recorded sound becomes very bad,

sometimes noisy become in the left mic only :As in the picture

and sometimes it become in both mic:As in the picture

I expect from you distinctive and fast answer

Please accept my thanks in advance

The internal mics are pretty noisy, but they shouldn't be that noisy that you can't use the sound recorded. Is there perhaps a ventilation system in the rooms? Also, what is your recording level? Perhaps you're recording too loud or maybe listening too loud. Was there an attached image? I didn't see any

Normal room ventilation system Mic among recording level (100-89) Even if it were reduced to 30 recording indicator remains high I can not add a"illustration picture" because I am a new member.........Sorry for any Linguistic errors – Hekmat Adnan Feb 21 '12 at 18:20
