Because Audio waves move as sound waves through air as condensations and rarefactions or slight compressions and partial vacuums of gas molecules and can be stopped by the walls of a house.

What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
How audio signal convert into electrical signal?
microphone............
What Distortion or unwanted noise in audio signal?
Noises present in audio signal may be of various kinds like environmental noises, transmission noises etc.
How is Sound produced in a audio devices?
Physical vibrations of speaker cones or metal plates by electromagnetic coils connected to the audio output AC signals from the audio amplifiers.
How can you transmit voice signal using ask modulation?
The only way is to digitize the audio signal and send it as data
What is an electromagnetic signal that is sent in a particular direction?
electromagnetic signal

How do a transverse wave carry audio signal?
the audio signal is put on transverse wave .
This converter is for audio only, not for a TV signal.?
This converter is for audio only, not for a TV signal.
How audio signal convert into electrical signal?
microphone............
What is normalize audio?
The relative amplitude (loudness) of an audio signal can vary from soft to very loud. When you normalize an audio signal, you adjust the overall average amplitude to be about same throughout. An audio signal is 'normalized' to a specific numeric value, measured in decibels (e.g. -4db).
What is audio signal range?
20Hz to 20kHz
What is auxiliary audio input?
Simply put, it is an "extra" audio input that allows a device to accept the audio signal from an external audio player.
Why is amplitude of demodulated FM signal much less than modulated signal?
because demodulated FM is an audio signal, which the frequency is much smaller that is why it can be transmitted alone. It need carrier which has large frequency. Modulated signal is an audio signal + carrier that is why the amplitude is higher.
What is the frequency of a signal whose wavelength is 1.5 meters?
The answer will depend on what type of signal it is: acoustic, electromagnetic and in what medium the signal is propagated.
What Distortion or unwanted noise in audio signal?
Noises present in audio signal may be of various kinds like environmental noises, transmission noises etc.
What is a balanced and unbalanced audio?
Balanced means that the audio signal is going evenly to each channel. (Left and Right)Unbalanced means that the audio signal is going unevenly to channel. Balanced audio means that neither signal carrying wire is used for the ground. The ground is a separate conductor. Most of these audio cables have 3 wires inside. Unbalanced means that one of the signal carrying wires is also is used for ground thus a 2 wire cable.
