Walking briskly typically falls under the moderate-intensity category of physical activity, where you might feel your heart rate increase and break a sweat. It is more intense than a leisurely stroll but not as intense as running.

moderate


What unit is intensity level?

Intensity level is typically measured in decibels (dB). It is a logarithmic measure of the power or amplitude of a sound wave, where an increase of 10 dB represents a tenfold increase in intensity.


What is the relationship between sound intensity level and the perception of loudness?

The relationship between sound intensity level and the perception of loudness is that as the sound intensity level increases, the perception of loudness also increases. This means that the louder the sound, the more intense it is perceived to be by our ears.


How does the intensity of a 40-decibel sound compare to the intensity of a 20-decibel sound?

Given: Sound intensity level LI1 = 40 dB and sound intensity level LI2 = 20 dB. Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing) Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level) Get sound intensity I1 when entering sound intensity level LI1 = 40 dB: Sound intensity I1 = Io×10^(LI/10) W/m² = 10^−12×10^(40/10) = 0.00000001 W/m² = 10^−8 W/m². Get sound intensity I2 when entering sound intensity level LI2 = 20 dB: Sound intensity I2 = Io×10^(LI/10) W/m² = 10^−12×10^(20/10) = 0.0000000001 W/m² = 10^−10 W/m². The sound intensity I1 = 10^−8 W/m² is 100 times more than the sound intensity I2 = 10^−10 W/m². The sound intensity level LI1 = 40 dB is 20 dB more than the sound intensity level LI2 = 20 dB.


What is the intensity of a sound wave called?

The intensity of a sound wave is called sound intensity. It measures the amount of energy transmitted by the sound wave per unit area. Sound intensity is measured in decibels (dB).
