Razr2 V9 on AT&T Cell Phone Review - Audio Quality

Mark Brezinski
Published on October 02, 2007 Comment on this






Regardless of the extras handsets come packaged with nowadays, a phone's primary job is making calls. Audio quality will most likely be the feature of the phone you'll notice most. And for outgoing calls, if you've ever been told you sound completely different on the phone then you understand that initial moment of, "Wait, what do I sound like?" Here we try to clear up those issues before you have an important interview hang up because your voice sounds like an impostor. We test audio quality using the same equipment and software manufacturers use to test phones. Our hardware, HATS, is a head and torso simulator that simulates human hearing and speech frequency. Our software is SoundCheck, which analyzes the frequencies and measures them against industry standards. If you want to know more about our testing, click here.

Sound Receive Frequency Response (8.85)


The V9 did a good job relaying the frequencies it received. As you can see from the graph, the line stays in between the limits right until the very end, where it drops off a bit before it should. This means the highest frequencies might sound slightly muffled, but you probably won't notice. Overall, a great job.

Sound Send Frequency Response (8.28)



Again, the V9 performs admirably. Though the graph isn't as close to bisecting the limits as the first one, the line still remains within the limits throughout. Phones typically do a worse job with your own voice as opposed to that of an incoming caller, which is why the V9 was able to perform worse and still outscore all the comparison models. Again, however, the graph takes a plunge near the end, which means that your voice might sound a little clipped.

Handset Side Tone (9.72)



Side tone refers to the amount of your own voice the phone plays back to you over the speaker. If you can't hear your voice you have a tendency to speak louder, and if it sounds too loud, you'll feel as though you should whisper. The ideal side tone is 18 decibels, which the V9 comes incredibly close to with 17.72. This score rounds out a great set of results from the V9.
