What causes electrical feedback?
Electrical feedback occurs when a portion of an output signal is fed back into the input of a system, creating a loop. This can happen in various electronic circuits, such as amplifiers, where it can enhance or stabilize performance. However, if the feedback is excessive or improperly managed, it can lead to unwanted oscillations or distortion, commonly known as feedback noise. In audio systems, for example, this often manifests as a loud screeching sound when a microphone picks up sound from a speaker it is connected to.
What causes guitar feedback when not touching the strings?
Guitar feedback occurs when the sound from the amplifier is picked up by the guitar's pickups and re-amplified, creating a loop of sound. This can happen even when not touching the strings due to the proximity of the pickups to the amplifier or other sources of sound.
What is a PA system?
PA stands for Public Address system. A PA system is a sound reinforcement setup in which audio is being distributed. This term is sometimes used interchangeably with "sound reinforcement system", though PAs are generally used in smaller venues or only for the reproduction of speech/prerecorded music.Some examples of PA systems include:SchoolsHospitalsChurchesRetail storesTrain/subway stationsSmall clubs/bars
What does pumping effects mean in the sound reinforcement system?
This is a fault also known as breathing. Too much sound compression can cause the compressor/limiter circuit to engage and disengage rapidly.
What did wolfgang ahnert invent?
A new approach to sound reinforcement and sound systems.
What is feedback in reference to electric guitar?
Feedback is the interference that is caused when the sound from the amplifier hits the guitar and creates an unpleasant sound.
What causes the pressure sound you hear when you turn off the car air conditioning?
That is the normal sound of the pressure equalizing in the system.
What has the author Wolfgang Ahnert written?
Wolfgang Ahnert has written: 'Sound reinforcement engineering : fundamentals and practice' -- subject(s): Acoustical engineering, Loudspeakers, Public address systems 'Sound reinforcement engineering'

What causes squeal or noise in a sound system?
A loud "squeal" or "screech" - also known as "feedback noise" - is usually only generated if there is an audio input device for an amplifier, for example a microphone, that is being used too close to an audio output device for the same amplifier, for example a speaker.
What is the full voice meaning of the term "resonance"?
The full voice meaning of the term "resonance" is the reinforcement or amplification of sound waves, vibrations, or frequencies caused by sympathetic vibrations in an object or system.
