This will not damage the hearing of the ears, but will protect the hearing.
The technical principle used by BOSE's noise reduction headphones is: there is a microphone on the headset that collects sound, especially low-frequency noise. Through special processing, it emits a sound wave that is opposite to the low-frequency noise to offset the low frequency. Noise effect. Therefore, many people feel uncomfortable when they put on noise-cancelling headphones for the first time. This is because the air pressure outside the ears is directly offset and the air pressure is felt. This will not damage the hearing of the ears, but will protect the hearing. When listening to music in a quiet environment, even the smallest sound can be heard clearly.
