Most Powerful Pieces Of Technology Of Their Kind

Loudspeaker

The most powerful speaker ever constructed is the HS-60, an acoustic hailing device produced by the Wattre Corporation in the US. From one meter (3.3 ft) away, it produces a noise level of 182 decibels (dB), slightly above the volume that kills hearing tissue. For comparison, the loudest recommended level of noise for someone wearing hearing protection is 140 dB. The HS-60 created 140.2 dB at a distance of 128 meters (over 400 ft). It’s loud enough that if it was producing a voice transmission, you’d be able to hear it clearly over three kilometers (two miles) away.

Unfortunately, it’s not currently available for purchase, so you’ll have to make do with its slightly less-powerful cousin, the HS-40. The HS-40 is able to transmit a voice clearly over half that distance and is used for hailing ships and making security announcements over large distances.
