LG Voyager Cell Phone Review - Audio Quality
To test the call quality of phones we use the same professional hardware and software that many of the manufacturers do. To simulate the human ear we use a Head and Torso Simulator (HATS) and to analyze the sound produced we use Listen Inc's
SoundCheck software. For more information on how we test see
this article.
Sound Receive Frequency Response (7.84)
The chart above illustrates the quality of sound received by the LG Voyager. The Voyager's performance is indicated with a blue line while the limits we test against are in red. You can see that the Voyager did a decent job of staying within our limits with only a couple of minor aberrations. This means that you should have minimal problems understanding the voices on the other end of a phone call. You can see below that that Voyager's performance in this test isn't the best we've seen, but apart from the iPhone it is certainly amongst a collection of very solid phones.

Sound Send Frequency Response (8.51)
In this test we try to measure the quality of sound sent by the Voyager. This is how you will sound to those on the other end of a phone call. The chart above indicates the LG Voyager's performance with a blue line while our limits are again indicated in red. You can see that the LG Voyager did pretty well in this test as it doesn't fall outside of our limits at any point. We were quite pleased with the Voyager's performance; your voice should sound clear to those on the other end of the call. You can see below that the Voyager put up the best score in this test amongst our comparison phones.

Handset Side Tone (9.63)
The equipment we use for testing side tone is currently not functioning properly. In the interest of releasing this review in a timely fashion, we've decided to simply not score the Voyager's side tone for the time being. We will update this section later as soon as we can get our equipment back in working order.
Update: We have fixed our problems with the side tone test. Side tone is the small amount of your own voice that the phone pipes back into your ear so you can hear how loud you are speaking. Our target for side tone is -18 decibels; the LG Voyager scored 17.63 decibels, which is just about right on. You can see below that the Voyager put up one of the best side tone scores amongst our comparison phones.
