age hearing loss comes in one way or another. So I set the volume on the headset to about 50% (there are 15 levels of volume to the headset so I set it to 7) and my computer master volume to 50%. This level of sound should work well from all test.
Is a two part test with sound files testing the bass and treble extensions. The bass extension test your headphones 10 Hz to 200 Hz and the treble extension test your headset 22 kHz to 8 kHz. Good headphone will go as low as 20 Hz on the bass test, and will have frequencies up to 20 kHz.
The bass test I could hear the frequency as the 20 Hz was announced so the test was good. It was a smooth bass sound but not a heavy bass.
The treble test I could hear the frequency just after 19 kHz. This is slightly lower than good headphone rating but I might add age and past work history will have an effect on the test. The started off with a slight static treble but smooth to a clear high pitch by 16 kHz to 8 kHz.
The dynamic range test goes between the quietest and loudest signals in which this case is white noise to speech telling you how far below dBFS (decibels below full scale). The test is not related to a specific function of the headset, but it helps to test isolation within a noisy environment.
I personally could hear the Voice Over speech as low as 60 dBFS.
The quality test, tests the bass frequencies to check how well the speakers are made. If they are poorly made they will have a rattling or buzzing noise.
The Hammo TV headset had no buzzing or rattling. Very smooth bass not over bearing
The driver matching reproduces a stereo frequency to both earpieces at the exact identical level. The tone should feel as though it is right in the middle of your head.
The headset was very well matched through the whole test which was up to 10 kHz.
The wiring test checks to makes sure the left wiring is connected to the left headphone & the right wiring to the right headphone.
The wiring was connected correctly.
The binaural test has two sets of wooden door knock. The recordings were captured by having a microphone in someone’s ear so that it collects the sound that reaches the pinnae, the external part of the ear. This works only with headphones and you are determining whether the sound is right next to you and how real does the wooden door sound.
The direct off set to the right door and the over the left shoulder sound of the left door sounded great
