Mysterious hum rattles American city as residents report sleepless nights and rising fear

A persistent, low-frequency hum has invaded the city of West Haven, Connecticut, according to many residents, leaving some shaken by an occurrence they're calling everything from mysterious to excruciating.

For some time, residents of this city on the coast of Long Island Sound have believed the source of the hum to be local industry, and they’re demanding a resolution. After circulating a petition and obtaining over 140 signatures, a group convinced the city council to spend $16,000 to hire a third-party acoustic firm.
