Noise cancellation in today’s noisy world is more important than ever. It makes all the difference to how much you enjoy the music pumping through your stereo. The market is awash with various noise canceling headsets.
How to shop for noise cancellation headsets
Frequency response (FR)
This represents the range of frequencies that the headset can produce. It is given regarding Hertz (Hz). It is usually in the range of 20-20,000 Hz. The lowest numbers represent the amount of bass. FR has no bearing on the quality of sound. It, however, determines the type of sound will pre-empt all the others. This is why different headsets have their strange sounds. The highest, the amount of treble. This is an area to consider as it affects the type of sound your headset will offer. If you want to experience more bass, go for a headset that supports low bass frequencies.
The type of cancellation
Noise cancellation headsets can either be passive or active. Passive noise cancellation involves stuffing up your ear canals with enough stuffing to block out all outside noise. They are efficient when the noise being blocked is not too loud. If you are looking for noise cancellation in a noisy place like the subway, go with active noise cancellation headsets. They emit frequencies that cancel out any outside noise. This gives you the privilege of only hearing sounds from your headset.
Total harmonic distortion (THD)
Noise canceling headsets should also sound good. THD is expressed as a percentage on the headset’s specifications. It is an estimated measure of the total amount of sound distortion you will experience at high volumes. Anything below 1% is acceptable. Lower THD implies few distortions. The fewer the distortion, the better the headset.
If you decide to purchase the active noise cancellation headsets, consider battery life. Batteries are imperative to these headsets. This is because they provide the power needed to produce internal frequencies to cancel out the external noises. Some do not work without batteries. This means that you cannot continue to enjoy your music when battery power dies down. To circumvent this, go for headsets that also offer passive noise cancellation. They will not be as effective on cancellation as when the batteries were powered up, but, you will still get to enjoy your playlist.
On the specification sheet, drivers are denoted in millimeters (mm). Drivers are what convert electric signals into sound waves. Good sound from your headset aids in the cancellation of outside noise. Larger drivers are associated with better sound. 40mm or bigger is an excellent size for a headset.
Look out for these things to buy a headset that will help achieve noise cancellation.
