Noise-canceling headphones: when do you need them?
Many are familiar with the situation: in everyday life you
are annoyed by the booming train or bus, crowds of people drown out every
conversation and then the construction site noise. For many, the solution is
very simple: headphones on, music on, world off! But the outside noise is still
annoying and you have to set the maximum volume to be able to enjoy the music
to some extent. However, this is no longer a relief for the ears, on the
contrary!
Many headphones are already built so that they can somewhat
isolate the sound. But if you really want to have peace (be it with or without
music), you can rely on noise canceling.

Noise-isolating headphones
In order to eliminate all of the noise sources mentioned
above, there is the option of using noise-isolating headphones. However, this
term should not be confused with noise canceling. Noise-isolating headphonesare passive noise-canceling. This means that the ambient sound is only isolated
due to the design of the headphones. No additional noise canceling technology
is installed. This category mostly includes over-ear headphones that only
surround the entire ear and thus (largely) isolate external noise, such as the
Teufel Massive.
But also custom-made or at least very well-fitting in-ear
headphones, such as the Move BT, can dampen the outside noise somewhat and thus
ensure quiet music enjoyment.
When talking about Active Noise Canceling (ANC), there is
always built-in noise canceling technology - such as our Real Blue NC. Small
(invisible) microphones are built into the headphones, which perceive all
outside noises. This ambient noise is processed by the headphone electronics,
whereupon an anti-noise is generated. This additional sound generated exactly
corresponds to the tones of the outside noise, but in the opposite phase
length. The ambient sound is simply eliminated by a counter sound. This methodworks particularly well at low frequencies, such as booming engine noises,
humming vehicles or noise. This means that noise-canceling headphones are
particularly suitable for traveling on buses, trains and planes. The
noise-canceling technique can also be used without music,
So that the microphones and the processing electronics can
work in active noise-canceling headphones, a separate battery is always
required, which can be recharged via USB, for example.
