Sony MDR-NWNC33 Noise Canceling Ear Canal Earphones For Walkmans, black





sony MDR-NWNC33 noise control is used in noise-cancelling headphones to decrease undesired background noise. This differs from passive headphones, which utilize methods like soundproofing if they want to at least reduce background noise.


It is possible to listen to audio content without turning up the volume too much thanks to sony MDR-NWNC33 noise cancellation. In a noisy environment, like an airplane, it can also aid in improving sleep.


sony MDR-NWNC33 Noise-cancelling headphones in the aviation environment boost the signal-to-noise ratio substantially more than passive noise attenuating headphones or no headphones, making it easier to hear essential messages like safety precautions.


sony MDR-NWNC33 Noise-cancelling headphones can enhance listening to the point where they entirely cancel out the influence of a concurrently distracting activity.


Active noise control, also known as ANC, is a feature of noise-cancelling headphones that eliminates lower-frequency sounds. A sony MDR-NWNC33 tiny amplifier produces sound waves that are precisely out of phase with the unwanted sounds after a microphone records the intended ambient sounds.

The sony MDR-NWNC33 canceling wave is weak when the noise wave’s sound pressure is strong (and vice versa). When opposing sound waves contact, they are “cancelled” or removed. The sony MDR-NWNC33  majority of noise-cancelling headphones on the consumer market use analog technology to create the noise-cancelling waveform in real time.

Other active products for noise and vibration control, however, employ soft real-time digital processing. In an experiment sony MDR-NWNC33 to assess how well lightweight earphones and headphones reduced noise to standard headphones and earphones, it was found that lightweight headphones performed better.

In-ear headphones performed better at minimizing noise than outer-ear headphones, according to the investigation.

Cancellation concentrates on repetitive, droning noises like traffic noise and is less successful with speech or shattering glass. Additionally, it is poor at reducing higher frequency sounds like spraying. To enhance the sound reduction across the frequency range, noise-cancelling headphones frequently combine sound isolation with ANC.

Without sound isolation, noise cancellation can be employed to make desired sounds (like voices) easier to hear. Due to the circuitry needed, passive noise cancellation cannot be used to reduce ambient noise, hence any references to it really apply to goods with sound isolation.

The majority of noise-cancelling headphones depend on sound isolation or soundproofing to keep higher-frequency noise from reaching the ear. Since higher-frequency sound has a shorter wavelength.

It would either require digital algorithms that would complicate the headphone’s circuits or locating devices that could detect and block it closer to the listener’s eardrum than is currently technologically possible.

The amount of noise that noise-cancelling headphones can block out is expressed in decibels. This figure may be helpful for comparing goods, but it does not fully convey the noise reduction at different frequencies.

By the 1950s, Dr. Lawrence Jerome Fogel created systems and submitted patents about active noise cancellation specifically in the field of aviation. This system was designed to reduce noise for the pilots in the cockpit area and help make their communication easier and protect hearing.

Fogel is considered to be the inventor of active noise cancellation, and he designed one of the first noise-cancelling headphones systems. Later on, Willard Meeker designed an active noise control model that was applied to circumaural earmuffs for advanced hearing protection. Noise-cancelling aviation headsets are now commonly available.

Thus, the earphone can definitely meet your needs.
