When recording a snare drum with a mic on the top and the bottom, a phenomenon known as phase cancellation can occur. Sound is a wave. A property of waves is that they can interfere with each other destructively and constructively. Imagine the sound waves caused when hitting a snare drum. The waves from the top of the drum will go into the top mic first, then the bottom mic. The waves from the bottom of the drum will go into the bottom mic first then the top mic. Because of the timing of the waves as they arrive at each mic, they will destructively interfere, and many of the frequencies integral to a good snare drum sound will be low in gain (volume). So a good audio engineer will use a phase reversal lead on the bottom mic. This is just like a normal lead, only the positive and negative pins have been reversed, and the phase cancellation will not occur.

What is recording phase of accounting?
Recording phase of accounting is to record the transactions into journal after transactions occured.
What is the phase change in a boiling point?
What is the phase change in evaporation
Who typically handles the data accumulation and recording phase of accounting?
The data accumulation and recording phase traditionally has been largely clerical; typically and appropriately, this has been called bookkeeping, which is still a common and largely manual activity,
How do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
What is it called to change states of matter?
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
Is a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
What phase change causes water to evaporate?
This phase change is called evaporation.
When a solid is heated it will usually change to this phase?
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.
What is a phase change example of?
When ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.
What is a change of substance from one state of matter to another called?
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
Is a Chang in a phase a physical change or chemical Chang?
A change in phase is a physical process.
Why does phase change occur in materials?
Changing the temperature or pressure of a material we can change the phase.
