Residential Noise Cancellation

Active cancellation probably won’t work. You need a clearly definable source, a point source preferable. It might be difficult to say where the source is in a house.

Active cancellation probably won’t work. You need a clearly definable source, a point source preferable. It might be difficult to say where the source is in a house. Also, the cancellation only works on a small area where the listener stays put. That’s why it works in cars, however, you need a noisy car. Lotus cars had a system for cars but in their demo’s they would rent a cheap car. It was a system that plugged into the radio. The active cancellation head phones work because they only have to cancel at your ear, a small area. I like masking. It’s low cost and small portable systems are readily available. Otherwise one could purchase an active cancellation head phone but that wouldn’t’ be comfortable to sleep with.
