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.
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
microphone............
Noises present in audio signal may be of various kinds like environmental noises, transmission noises etc.
Physical vibrations of speaker cones or metal plates by electromagnetic coils connected to the audio output AC signals from the audio amplifiers.
The only way is to digitize the audio signal and send it as data
electromagnetic signal

the audio signal is put on transverse wave .
This converter is for audio only, not for a TV signal.
microphone............
Yes, a radio transmitter converts an electronic signal (such as audio from a microphone) into radio frequency (RF) waves. These RF waves are then transmitted through antennas as electromagnetic radiation, which can be converted back into sound waves by a receiver like a radio or smartphone.
20Hz to 20kHz
Simply put, it is an "extra" audio input that allows a device to accept the audio signal from an external audio player.
You can create a sound wave from audio by converting the audio signal into an electrical signal using a microphone, then amplifying and transmitting it through a speaker to produce sound waves that can be heard.
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.
Noises present in audio signal may be of various kinds like environmental noises, transmission noises etc.
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.
