What is Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity
What is the relationship between wave amplitude and intensity?
I=a2
What is Decibel level?
A unit used to measure the intensity of a sound or the power level of an electrical signal. Someones voice could raise by a decibel.
How do the amplitudes of a decibel sound and a 100-decibel sound compare?
The power or intensity of the louder one is 10 billion times the power or intensity of the softer one. Since the power or intensity is typically proportional to the square of the wave amplitude, the amplitude of the louder one is a mere 100,000 times the amplitude of the softer one.
What does dB mean in physics?
dB stands for decibel and is used to measure sound intensity in acoustics
What is Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity
What is the unit of sound intensity?
Decibel
Decibel is a unit of?
Sound intensity
How the term intensity decibel and amplitude are related?
They are all measueres of sound waves. Amplitude is the term for the maximum difference in pressures between the peaks and troughs of a sound wave. Intensity is a measure of the energy content of a wave, and is proportional to amplitude squared. The decibel is an anthropic (based on human senses) measure of sound intensity, proportional to the logarithm of intensity.
What is the relationship between amplitud and intensity?
I=a2
What is the name of the unit used to measure the intensity of a sound?
a decibel
What is a unit used to measure the intensity of sound called?
decibel
What does the unit decibel measure?
The ratio between two quantities, usually quantities that somehow measure power, or intensity (power / area).
What is the relationship between wave amplitude and intensity?
I=a2
A decibel is a unit used to measure the?
decibels measure the intensity of sound.
How does the intensity of a 40-decibel sound compare to the intensity 20-decibel sound?
100 times. Each bel (10 decibels) is ten times as loud thus 20 to 40 is 100 times.
What is Decibel level?
A unit used to measure the intensity of a sound or the power level of an electrical signal. Someones voice could raise by a decibel.
