Second microphone blocking voice - Nexus One Q&A, Help & Troubleshooting

When I put my phone between my head and my shoulder, so I have both hands free, people tell me they can hardly hear me.
I guess this is because the phone's second mic, the one on the back of the phone, is being blocked by my shoulder.
IMO, the phone shouldn't block my voice, since it 'should' use the first mic.
I know noise cancellation is being used, but should it cancel my voice when the second mic is being blocked?
Anyone else noticed this, or knows a fix?

Yes this is normal behaviour unfortunately. that second mic is required to be open for sound to be clear regardless of outside noise.
If your rooted, you can disable the feature through a code edit in the build.prop

"Tin can" issue

I'm not sure if anyone else has had this, but this is the first phone i've come across with this issue...
Whenever I'm gaming or something and my phone rings, I instantly pick up and balance it between my ear and my shoulder when i talk (you know, like old school phones when multitasking)...
But whenever i do this people say i sound like I'm talking in a tin can...
Is the second Mic (to drown out background noise) to blame?
make sure that mic isnt blocked. if you put it on your shoulder it will happen
No matter how I hold the phone people complain about this.
People have actually asked me what kind of ****ty phone/reception I have because the audio quality is so bad.
it may be a bad mic. have you always had this? maybe you should call gtc because all the major phone reviewers noted the nexus had one of the best quality calls of any phone. it should not sound that bad
Mine sound great at least. I know this since both me and my brother has a N1. Really good sound quality from my experience.
I've read this same issue before on the Google Android forum. Apparently it has something to do with the secondary mic and how the shoulder conducts sound thereby activating the noise cancellation of your own voice.
I also talk this way and don't have this issue atleast no one complaint.
I am waiting for my warranty replacement due to come in today.
Will report if that fixes it.
Have you guys tried using like a bluetooth headset or wired set to see if it's really the mic issue?

Thats the conclusion i came to... guess i'll start looking into a Bluetooth headset

[Help] Mic doesn't work in calls

i can use voice recording or voice to text just fine. i can also make phone calls in speaker phone mode just fine. but when i turn speaker phone off the person on the other end can BARELLLLLY hear me
ugh so i've been trying to test it
i left myself some voicemails using the phone
if i talk normal i hear nothing with an occasional click or something. if i take my finger and rub it on the noise canceling mic while talking i can sort of hear myself talking but its really low and garbled sounding, and of course if i switch to speakeprhone then i hear myself fine
this sucks, its obviously some kind of software issue. does the phone not use the secondary mic for noise canceling during speakerphone? that would explain the issue i guess.

The mic on my first N1 was broken so it might be a hardware issue.
its either software or the secondary mic is broke and is causing it to filter out everything, because the main mic works great on speakerphone
this sucks

[HELP] Call quality over VOIP and in general?

Need some help guys and girls with my Z1 and also my wife's (they have the same issue) to let us know if this is normal for these phones or not?
List of issues below which we both have with the call quality.
1. When using viber or skype over WIFI the volume is turned up to the max on my phone but I can barely hear anyone even in a very quiet room.
2. When outside in a fairly noisy environment (town for example) I cannot hear ANYTHING apart from a muffled muted sound.
3. With the volume turned up to the max we can hear an echo so to speak a split second later with what we have just said.
4. The other person on their phone says sometimes it's very clear but normally it sounds like you are on speakerphone and/or very far away from the ear piece.
I have played around with the call settings by turning off noise suppression, playing with the EQ and everything else I can think of but so far I have not been able to fix it.
NOT interested in rooting whatsoever as if I cannot find a solution I may have to look for a new phone.
P.S I love everything else about this phone, the build quality, the camera just want to be able to use it to make phone calls.
I have a similar issue where if i'm holding the phone between my ear and my shoulder ( no hands on the phone ) , the person on the other end of the call says the same thing you've mentioned in point 4
"4. The other person on their phone says sometimes it's very clear but normally it sounds like you are on speakerphone and/or very far away from the ear piece"

Problem with my microphone

People keep saying they cannot hear me when I talk to them. It's like I'm speaking through a can, from a distance. My warranty is not valid anymore as the phone is rooted, but I know it's been like this for a while, way before I rooted it. It's like water is stuck in the microphone somehow, or that an internal piece may have been depositioned and blocking the mic.
Is there anything I can do to solve this? Like a 3rd party app that increases the mic volume?
Thanks
Your Warranty is not voided because of Root. If you bootloader is locked you can just revert to stock.
BTW, Z1 have 2 microphones, are you sure you holding in the right position the phone? :laugh:

So if I relock my boot loader with stock ROM the warranty will still be void?
2 microphones? As in one for calls and one for the camera? The camera mic works just fine but the one for calls seems to be completely broken no matter how I hold my phone. I just had a phone call and when I answered, the person on the other end could not hear me at all. I had to switch to speaker phones so it could use the camera mic instead.
EDIT: Okay, so I just tried to set my own voice mail in order to playback my calling voice. I'm not joking, I sound just like Stephen Hawking except that you can barely hear what I'm saying. It is very robot like and distorted. Also, it seems like there is a voice recognition thing on, which means whenever I stop speak, the mic will turn off to reduce ambient noise. However, this also removes the first word I say when it activates the mic again upon voice recognition. I turned the noise cancelation setting off but no major difference.
And btw, the problem only seems to exist when I'm in a call, not when recording my voice with an app like WhatsApp or any sound recorder from Google Play. Even the built-in voice recorder works fine. Does this have something to do with my carrier?

There is not 1 for camera and 1 for calls. There is 2 microphones, 1 at the bottom of the phone and one on top behind call speaker. They both working with any application to reduce noise in phone calls or recordings. Just search on Google, is not so hard.

As I don't have this problem in any circumstance I cannot tell, play with the settings to understand if you will get better sound quality.

Maybe but I don't know, as the problem persist then I will return the phone to your carrier, let them know the problem and repaired or replaced the phone.

Question Clear Calling blocking voice of younger kids when using phone?

Has anyone else had an issue with Clear Calling blocking the voice young children? Here is what I mean. Because Clear Calling blocks out ambient noise, it would as designed, mute/reduce the sound of my kids talking behind me when I am on a call, however, I have noticed that it seems my 9 year old is also muted when he is the one making the call, and should be the primary voice. For example, he will call my wife from my phone, and despite the fact he will be speaking into the phone properly at a normal volume, my wife will hear nothing on her end of the call, as if he isn't even talking, yet if I speak over him, she will instantly hear me just fine.
Curious if anyone else has encountered this and if Googles algo for Clear Calling just automatically blocks sounds in a particular frequency band. Just really inconvenient to turn Clear Calling off just so that he can use the phone.

Tell the kid to try talking in a deeper voice, bet you it will work then. It really is just the stupidest algorithm imaginable, just cuts things out that are beyond the normal adult human voice frequency range.
