A two-way radio can be susceptible to interference from electrical noise generated by a some nearby electrical equipment. This noise may interfere with the regular operation of mobile radios. If the radio signal is strong, the noise component may not affect communication, but if the signal is weak, noise levels can create a hindrance in communication and hence noise reduction becomes very important.

Some radios have a noise filtering feature that can reduce unwanted noise and help in effective communication.
