What else can I help you with?
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.
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".
What type of wave cannot be generated in the absence of a medium?
Sound waves can't be generated in a vacuum.
Why d in small in decibel?
The "d" in decibel represents Alexander Graham Bell, who was an influential scientist in the development of the decibel scale. The decibel scale is used to quantify the intensity of sound or the power level of an electrical signal on a logarithmic scale.
What is the difference between the major and minor blues scale?
The major blues scale has a happier sound, while the minor blues scale has a sadder sound.
What is the relationship between sound intensity and the logarithmic decibel scale?
The relationship between sound intensity and the logarithmic decibel scale is that the decibel scale measures sound intensity levels in a way that reflects the human perception of sound. Sound intensity increases exponentially on the decibel scale, with each 10 decibel increase representing a tenfold increase in sound intensity.
What is the Measurement of sound energy?
Sound energy is typically measured in decibels (dB), which is a logarithmic unit used to quantify the intensity or power of sound. The decibel scale is commonly used to measure the loudness or volume of sound.
What is the relationship between sound pressure level and the perception of sound in a dB scale?
The relationship between sound pressure level and the perception of sound in a dB scale is that as sound pressure level increases, the perception of sound also increases. The dB scale is a logarithmic scale that measures the intensity of sound, with each 10 dB increase representing a tenfold increase in sound intensity. This means that small changes in sound pressure level can result in significant changes in the perception of sound.
What does the term decibel mean?
The decibel is a unit used to measure the intensity, or power, of a sound. It is a logarithmic unit that compares the power of a sound to a reference level. The decibel scale is commonly used to quantify sound levels and express changes in sound intensity.
How is the energy of a sound wave related to its measured value on a decibal scale?
The decibel scale is a logarithmic scale. An increase of 10 points on the decibel scale means that the energy increases by a factor 10; an increase of 20 decibels means an energy increase by a factor of 10 x 10 = 100, etc.
