In undertaking our project, we discovered numerous real world applications of the headphones.

First of all, noise has been known to cause stress. Loud noises will give you headaches and make you feel unwell. Constant noise can also give you unhealthy stress that builds up over a long period of time. Headphones like ours will decrease the effects of constant background noise.

Aside from dampening sound for increased relaxation at home, headphones such as these may be useful in speech therapy and travel situations.

People with stuttering problems tend to stop stuttering when they can no longer hear themselves. In speech therapy, stutterers often utilize sound-canceling headphones to help them overcome their impediment.

When traveling, the low frequency noise (infrasonics) is a factor in increasing the fatigue a person experiences on a trip. By utilizing sound-canceling headphones, a traveler can diminish the amount of fatigue s/he feels.

Finally, it has been speculated that infrasonics can affect the heart and cause heart dysrhythmia. Low-frequency sound cancellers are therefore important for people who live near airports or bridges, which both give out a lot of low-frequency sounds.
