The N75 is a phone that has plenty of features, but it's still a device whose primary job is to make phones calls. So how good do the calls that it makes sound? To test the quality of the calls, we use professional testing equipment; a HATS (Head and Torso Simulator) that simulates the human head and ear, and a sound analysis program called SoundCheck. This combination allows us to analyze the quality of the sound that the phone both sends and receives. For more information on how we test cell phones, see here.
Sound Receive Frequency Response (8.73)
The N75 scored highly in our test of the sound it receives, such as someone talking to you over the phone. We test the frequency response of the phone (shown by the blue line) and measure this against the limits that are defined by a standard set by a group of international audio experts (the red lines). The N75 did well in this test; the frequency response was well within the limits, so voices should sound clear and understandable on calls coming into the N75
Sound Send Frequency Response (7.57)
Handset Side Tone (6.85)
