What ever happened to these? They sure would be helpful now a days with loud talkers being the number one annoyance in the office. The Voice Silencer lets you talk in secret.
Your telephone conversation can be made inaudible to others in the same room if the phone is equipped with a new mouthpiece that prevents sound from escaping. It is easily attached to any hand instrument and fits snugly around the speaker’s lips. There is no distortion of the voice.
