About Noise Canceling
The internal microphone embedded in the headphones picks up the ambient
noise. The player generates an antiphase sound wave against the ambient noise
to reduce it. The Noise Canceling function can reduce the unwanted ambient
noise especially in a vehicle such as an airplane, train, bus, etc., allowing you to
enjoy music at a low volume.
1 The waveform of the ambient
noise (original sound).
The internal microphone embedded in
the headphones picks up the ambient
noise. Then, the Noise Canceling circuit
analyzes the waveform of the noise.
2 The antiphase waveform
against the noise.
The player generates the antiphase
waveform against the noise to
cancel it out.
3 The composite waveform.
Two waveforms have
canceled each other out.
The original waveform and antiphase
waveform combine to cancel each
other out, reducing the ambient
noise.
Notes
If the supplied headphones are not used properly, the effect of the Noise Canceling
function may be degraded. To make the most of the function, use the correct size
earbuds to fit your ears and insert the headphones into your ears snugly.
The Noise Canceling function mainly reduces the ambient noise in the low frequency
bands and has no effect against the ambient noise in the high frequency bands. It has no
effect on some sounds.
D
o not cover the microphone part of the headphones with your hands, etc., otherwise
the Noise Canceling function may not work.
Microphone
Y
ou may hear a slight noise when the Noise Canceling function is active. This is
operational noise of the Noise Canceling function and not a malfunction.
