Noise cancelling headphones are something that most of us have heard off of but – partially due to price – most people haven’t tried them out and are unsure what they are. At first look you’d think it was simple – block the ear and you can hear less. That type of noise cancelling does exist but the HC31’s use something called active noise reduction or ANR. Sound travels in waves and the interesting thing about waves is that you can cancel them out with an opposite wave. Headphones with ANR have a microphone and analyze sounds going on around them and put out an opposite waveform. For the listener, sounds seem to get quieter.
The Panasonic RP-HC31 Noise Canceling Headphones capture surrounding noise and reverse the signal's wavelengths. The result? Noisy peaks are reversed, banishing background sound from your listening experience.
Noise canceling headphones enable a more immersive listening experience whilst protecting the listener's ears from excessive peaks of noise. By blocking background noise, music is clear and prominent even at low and mid-level volumes.
These headphones are designed to attenuate low-frequency inconsonant noise of 1,500 Hz or less. They do not have a great effect on relatively high-frequency components such as automobile horns, telephone rings or the human voice.
