Why do different frequencies not interfere?
That’s the reason why you hear beats—the sum of the two waves has a different overall frequency from either of the two waves. But since the two waves do not have the same frequency, the phase between them does not stay constant, so perfect constructive interference and perfect destructive interference are not possible.
What happens when two sound waves interfere?
When two or more sound waves occupy the same space, they affect one another. The waves do not bounce off of each, but they move through each other. The result is a wave that has twice the amplitude of the original waves so the sound wave will be twice as loud. …
How do I resolve radio interference at a radio station?
Google the station (or look it up in your paper Yellow Pages, if you still live in the 20th Century). Call them, tell them you’re experiencing radio interference and ask to talk with somebody from the Engineering department. They will try to help you resolve this situation.

What are the rules for merging TV stations?
FCC rules effectively prohibit a merger between any two of the big four broadcast television networks: ABC, CBS, Fox, and NBC. An entity is permitted to own up to two television stations in the same Designated Market Area (DMA) if either:
How many radio stations can a company own in one area?
Limitations on the number of radio stations a single entity may own in an area are based on a sliding scale that varies by the size of the market: In a radio market with 45 or more stations, an entity may own up to eight radio stations, no more than five of which may be in the same service (AM or FM).
