Panasonic RP HC300 Noise Cancelling Headphones work against ambient noise, using active noise control (ANC). Reducing more than 18 dB at 300 Hz is possible with noise cancelling headphones. Excessively high volume would be unnecessary while listening to music; noise cancelling technology will make it unnecessary. Vehicles, air conditioners, and the like make environmental noise that noise cancelling headphones can reduce by an eighth. Soundproofing against higher frequency noise accompanies the ANC in Panasonic noise cancelling headphones. One R03/LR03 AAA battery can provide power for noise cancelling headphones to generate antinoise signals. Panasonic noise cancelling headphones are intended to counteract continuous ambient sound, like the sound in an airplane cabin. Rapidly changing audio signals such as human voices, telephones, or car horns may be expected to stay mostly intact.
