: {{w|Squelch}} is a feature of radios (CB, ham, scanner, etc) which quiets background noise when no usable signal is present. It cuts off audio completely when only noise is present. As different environments can have differing levels of background noise, an adjustment such as a knob is required to set the level at which the squelch circuit deactivates and lets audio through ("opening" or "breaking" the squelch). This feature already exists in audio call software but hardwiring it to a knob on the outside of the phone is probably excessive. For a smartphone, perhaps this knob could control the "signal-to-noise" ratio of your Facebook feed or other social media platforms. It takes the place of the headphone jack, replacing the normal hole with a small knob. | : {{w|Squelch}} is a feature of radios (CB, ham, scanner, etc) which quiets background noise when no usable signal is present.
