What Is Acoustic Coupler?

The Acoustic Coupler is a device that allows you to connect your phone to your computer, which is the best thing ever. It's like a modem, but for the phone. And it's got a lot of other uses besides just connecting your phone to the Internet. It's also called an acoustic coupler because it picks up audio signals from a handset and converts them into electrical signals that can be read by the computer or terminal device. So if you're in a noisy place or don't want all of your conversations recorded, this is the perfect solution! In the 1970s, acoustic couplers were all the rage. They were fast and furious, and everyone wanted to get in on the action. But then modems came along, and their speed and reliability made acoustic couplers look like a relic of a bygone age. Acoustic couplers were invented in 1874 by Alexander Graham Bell. They were used as an alternative to hard-wiring telephones to a wall jack and served as a way for users to connect two telephone devices without being tethered to an electrical outlet. The problem with acoustic couplers was that they were not very reliable – they were susceptible to noise interference and tended to drop connections more often than not. They also transmitted at speeds of up to 300 baud – which was pretty much the limit of their capabilities at the time. Modems came along in the 1960s, but because they were connected through serial ports on computers rather than over phone lines, they weren't compatible with acoustic couplers until 1982, when AT&T sold its Western Electric subsidiary (which owned Bell Systems) as part of an antitrust settlement with federal regulators following years of antitrust litigation against them over monopolistic practices related to long-distance telephone service provisioning (among other things). So next time you're looking for something to do with all those old phones lying around at home, think about what an acoustic coupler can do for you!
