Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
How to distinguish between characteristic impedance and input impedance?
The characteristic impedance or surge impedance belongs to uniform transmission lines.In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Input impedance is greater than to load impedance?
In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Why is output impedance kept low?
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Why input impedance is in parallel and output impedance is in series?
That is not the case. Scroll down to related links and look at "Measurement of input impedance and output impedance".
What is the acoustic impedenece of aluminum?
There is no acoustic impedance of an element. Size is important. The acoustic impedance Z is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments.
What is the acoustic impedance and density of B-stage resin (also called resolite)?
It means the B-stage of phenolic resin, the density has been answered already, but the acoustic impedance is still a mystery.
What is the main item that contributes to acoustic velocity options are density elasticity acoustic impedance or both the first two?
density
What is meant by the terms acoustic impedance and attenuation?
Acoustic impedance is the measurement that indicates how much sound pressure the vibration of molecules at a given frequency is generated. Attenuation refers to the gradual loss in intensity through a medium, such as light and sound in water.
What is the significance of end correction?
The significance of end correction is that it is used in the radiation acoustic impedance of a circular piston.
What is the physical significance of the impedance?
Impedance may refer to: the ratio of the voltage phasor to the electric current phasor, as in Electrical impedance, a measure of opposition to time-varying electric current in an electric circuit. Characteristic impedance, a measure of opposition to electric current propagation in a transmission line. Impedance matching and Impedance mismatch. Vacuum impedance, a universal constant. Electromagnetic impedance, a constant related to electromagnetic wave propagation in a medium. Mechanical impedance, a measure of opposition to motion of a structure subjected to a force. Acoustic impedance, a constant related to the propagation of sound waves in an acoustic medium. Linear response function, a general way to represent the input-output characteristics of a system. Scroll down to related links and look at an example: "Interconnection of two audio units".

What are the measurements of acoustic impedence?
The acoustic impedance of a material is usually measured in an Impedance Tube.This is a metal tube of 100 - 200 mm diameter, and 1.5 - 2.5 m in length. in the tube, a sample of the material is placed ay one end, with a metal plate behind.At the other end of the tube is a sound source emitting pure tones.Along the axis of the tube, a traveling microphone may be traversed, and this measures the nodes and anti-nodes of the sound along the length of the tube.From the magnitude of these signals and their placement along the tube, the acoustic impedance may be calculated.Mostly, it is only the sound absorption coefficient that is wanted.Mostly, this is measured of the behavior of a building material. But it may be measured of an air volume, or even of part of a musical instrument.It may be considered to be analogous to electrical impedance, which is a native property of space, or of a material, or of an apparatus.
