The line connected to your home telephone often carries noise and interference along with the audio signal. To improve the audio reception, fix the background noise that is interfering with the call. There are procedures that will fix the background noise, none of which requires extensive electrical skills. You just need a few supplies from a hardware store and an electronics supplier, along with a few tools found around the house.

  1. 1

    Remove the wall plate covering the telephone connector block with a Phillips screwdriver. Loosen the screws on the connector block inside the wall with the screwdriver. Unwind the telephone wires from around the screws. Scrape the exposed ends of the wires with the wire strippers. Spray the screws with electrical cleaner and lubricant spray. Attach the wires and tighten the screws. Replace the wall plate.

  2. 2

    Plug the cord of a noise cancelling headset into the phone accessory jack on the side of the phone or its base station. Rotate the audio knob on the headset's cord to minimise or remove the background noise during a conversation. Remove the headset's cord from the home telephone after the call has been made, or leave it attached for future calls.

  3. 3

    Unplug the telephone cord from the home phone. Plug the cord into the phone input on a line surge protector. Plug one end of a telephone cord into the phone output of the line surge protector. Plug the other end of the telephone cord into the home phone. Plug the power cord of the line surge protector into a wall outlet for power.
