Echoing and background noise on iPhone calls
Posted 5 July 2007 @ 10am in Troubleshooting
A number of readers have reported an issue where the iPhone generates echoing and background noise on the receiving end of phone calls. Most users reporting this problem describe a situation where “everyone can hear themselves in the background.”
Interestingly, the receiving end echo can sometimes be resolved by using the included headset mic, but may result in a situation where the iPhone user instead hears an echo.
Note that this issue has been extant with other phones as well, generally attributed to an issue with the carrier (AT&T in this case) rather than the device. In these cases, the problem is simply a bad connection, resolved by hanging up and initiating a new phone call. However, the echoing in particular appears consistent for some iPhone users regardless of connection quality.
One iPhone Atlas reader writes:
“I’ve read that the volume of the speaker on the iPhone is low - so is mine. But, when I turn up the speaker volume, it seems to turn up the gain on the microphone as well. Recipient s of calls from me complain that there is a lot of background noise.”
There are a few less-than-ideal workarounds:
- Turn down the iPhone volume
- Avoid cupping the bottom of the iPhone with your palm when not using the headset
- Use a Bluetooth headset
Experiencing a similar issue? Please let us know.

Echoes are a common problem on GSM networks. AT&T, T-Mobile are both GSM. The GSM network always generates a certain speech processing delay which results in echo. In order to prevent this echo, echo cancellers are used. Sometimes not very effectively, especially on busy towers, during heavy use periods.
