BlackBerry Curve 8320 Review - Audio Quality
To test the quality of audio sent and received by the BlackBerry Curve 8320 we use a combination of professional software and hardware that allows us to make precise measurements. A Head and Torso Simulator (HATS) is used to simulate the human head and ear, while sound is analyzed by Listen Inc.'s
SoundCheck software. This combination is used by many handset manufacturers in their own testing. To learn more about how we test see
this article.
Sound Receive Frequency Response (8.30)
The chart above is a measure of the sound received by the BlackBerry Curve 8320. This is how others will sound to you while using the phone. The blue line indicates the phone's frequency response, while the two red lines indicate the limits against which we test; a good phone's frequency response should fall between the two limits. As you can see, the Curve 8320 generally stayed within our limits, with small excursions at the very low end frequencies and a quick peak at the high end. These slight deviations won't affect the quality of sound you receive on the Curve very much, though. We were generally pleased with the performance in this test.
Sound Send Frequency Response (7.51)
In this test we measure the quality of sound sent by the BlackBerry Curve 8320. This is how your voice will sound to those on the other end of the call. The chart above again indicates the Curve's performance with a blue line, while the red lines are the limits we test against. As you can see, the Curve 8320 once again performed well, with its performance falling solidly within our limits. The only possible glitch is that sound drops off a little quickly at the high frequencies, which may make those with high voices sound a little clipped. Even there, however, it's just barely within our limits. The BlackBerry Curve 8320 performed as well as or better in this test than most of our comparison phones.
Handset Side Tone (9.88)
Side tone is the small amount of your own voice piped back into your ear by cell phones so you can judge how loudly you are speaking. Lower side tone means your voice will sound too low to you, and you will raise your voice to compensate. Higher side tone has the opposite effect. The BlackBerry Curve 8320's average side tone was 17.88 decibels, which is right about where we want it. Our ideal side tone would be 18 decibels. As you can see below, the Curve 8320 put up the best score of any of our comparison handsets.
