Can the electrical energy b generated from sound then how?
By means of devices known as "microphone" or "telephone".
When you double your distance from a speaker you lose how many db?
Sound pressure is inverse square law for distance, so doubling distance from a speaker cuts the power by 4. Since the db scale is 3 times log2 (power ratio), a reduction of power by 4 represents -6db.
The pH scale is used to?
The decibel scale is used to measure the loudness of sound.
Prove dbm plus dbm equals db?
The decibel scale is a logarithmic scale where each change in three dB represents a power factor change of two. (3 dB is power times two, 6 dB is power times four, 9 dB is power times 8, etc. Similarly, -3dB is power divided by two, -6 dB is power divided by four, etc.) Zero dB is assigned some arbitrary reference power. One example is 1 mV across 600 ohms. If you double the voltage into a constant resistance, the power quadruples, so 2 mV would be +6 dB, 4 mV would be +12 dB, etc. The letter after dB is the reference power. In the case of dBm, it means that 0 dB is 1 milliwatt, so 2 milliwatt is +3 dB, etc. There are many dB scales, such as dBa, used in sound measurements. Still, fundamentally, 3 dB is a doubling of power, -3 dB is a halving of power, so, for any arbitrary scale, say dBq, then saying +6dBq is saying a power four times higher than 0 dBq. In the end, dBm plus dBm is delta dB, with no scale.
What is application of transistor?
Application: 1.For amplification of sound. 2.logic switch 3 oscillation 4 power amplification.
Why you are generating power from thunder in large scale?
You don't generate power from thunder. Thunder is the sound wave produced by the lightning bolt.
Can sound be generated from electricity?
yes
What is the mechanism as sound is generated?
The acousic principle.
A difference between sound waves and seismic waves?
Sound wave is is generated by a vibrating object.Whereas, seismic wave is the vibration generated by an earthquake or explosion.
What do vibrations have to do with sound?
Sound is generated by vibrations from many sources and many kinds.
What type of wave cannot be generated in the absence of a medium?
Sound waves can't be generated in a vacuum.
The scale used to define sound intensities?
decibel scale
How is sound absorbed and reflected?
Generated by the sound source will be present in the soundwaves propagated from the surrounding air.
How are sound waves generated in the sun?
I would expect any movement of matter to cause some sound.
How is sound energy absorbed and reflected?
Generated by the sound source will be present in the soundwaves propagated from the surrounding air.
What determines the sound of a scale?
The keynote
Is the 'a' sound in the word 'scale' long vowel sound?
No, the 'a' sound in "scale" is a short vowel sound. The long vowel sound for 'a' would be like in the word "cake".
