Things to consider when buying Active Noise Canceling Headphones
1 The dBs of noise canceling is the most important number to consider along with the frequency range that noise canceling is functioning.
Is the noise canceling all active or is some of it passive? Passive noise canceling is obtained by covering the ears with an insulated material that stops sound from reaching the ear drum. You can get completely passive noise canceling headphones at hardware stores for use when operating equipment that generates loud noise. Passive noise canceling normally reduces the external noise over the entire frequency range.
Can the noise canceling be turned off when listening to music in a quiet environment?
2 The frequency over which the noise canceling will operate is the next most important measure. Low frequency sound has the greatest impact when traveling in planes, trains, buses. You want active cancellation from about 20 -2000 Hz.
3 Comfort - will they cover the ear and be hot? Are they heavy and tiring to wear for long periods of time when traveling?
4 Size is an important consideration, both when in use and when stored. Size should be considered if headphones are primarily intended for travel use. Are they compact and easy to carry when not being used?
5 Sound Quality when listening to music both with noise canceling on and with it turned off is an important consideration. What are dbs?
The decibel (dB) is used to measure sound level, but it is also used in electronics, signals and communication. The dB is a logarithmic unit used to describe a ratio. The ratio may be power, sound pressure, voltage or intensity. A sound which is 10 times more intense is assigned a sound level of 10 dB. A sound which is 100 times more intense is assigned a sound level of 20 db. A sound which is 1000 times more intense is assigned a sound level of 30 db.
