We do our tests in a quiet room taking sound measurements with the handset loudspeaker facing the microphone at a distance of exactly 1 m. For each test we make several consequent measurements - we usually disregard the highest and the lowest readings and we take the average value of the rest. Our readings with it are pretty indicative on how well the handset loudspeaker would fare with common music.The three tests are as follows: 1) A phone ringing. Teenagers would surely appreciate the handset that will allow them to crank up the volume as high as possible. This is an important test, since if you tend the use the loudspeaker for speakerphone purposes, loudness is really important, no matter if you are at the conferencing room, or in your car. Let us just point out that this test is not about the quality of the sound produced by the loudspeaker.We use an old-school ringtone, resembling the ringing of an old phone. A mild, relatively deep sounding loudspeaker that soothes the ear won't do well in this test.
Most modern handsets have a speakerphone function, sometimes advertised as a built-in hands-free.
Having the voice of the other calling party sounding loud and clear is obviously a must.
Teenagers on the other hand like to use the loudspeaker to listen to music on their own outings or get-togethers (yeah, we know the sound quality sucks).
So we got ourselves a nice piece of equipment - a digital noise/loudness meter in order to start measuring objectively that all-important aspect of modern handsets - how loud is the loudspeaker in realty.
The equipment in question is not a high-end one, but we really don't need one.
All we need for our reviews is a way to measure the maximum (peak) loudness level that our handsets reach.So, for the record, here is how our test setup goes.But stepping out of these scenarios, you would hardly need us telling you that every phone is as good as its ringing.After all, that's its primary job - alerting you of incoming calls.So one way or another, whether you use it for fun, conference calls or just for plain ringing, there is one single thing that's important - loudness.We've never dug into that in our reviews besides the casual subjective remark of whether the handset ringing is loud or not, but we decided it's time we took a more scientific approach.
