When a pin is dropped onto a surface, the sound is approximately 11 decibels. How many times greater than the threshold sound level is the sound of a pin drop? Round to the nearest whole number.

Suppose the purr of a cat has a sound intensity that is 340 times greater than the threshold level. Find the decibel value for this cat's purr. Round to the nearest decibel.

Which of the following is an acceptable operational definition for an auditory threshold?Question 1Answera.The lowest intensity of a sound, as measured in decibels, at which a participant reports hearing the sound 50% of the timeb.The lowest intensity of a sound, as measured in decibels, at which a participant always reports hearing the soundc.The lowest intensity of a sound, as measured in decibels, at which 50% of the participants report hearing the sound.d.The lowest intensity of a sound, as measured in decibels, at which every participant in an experiment reports hearing the sound

Decibels measure sound(a) intensity(b) frequency(c) loudness level(d) all of the above (8.5)

Select the correct answer from the drop-down menu.The formula 𝛽=10⁢log⁡(𝐼𝐼0) is used to find the sound level, 𝛽 , in decibels (dB), of a sound with an intensity of I. In the formula, 𝐼0 represents the smallest sound intensity that can be heard by the human ear (approximately 10-12watts/meter2 ).The sound level on a busy street is 70 dB. What is the sound intensity on the street?The sound intensity on the busy street is watts/meter2 .

A child complaining of hearing loss is found to have a auditory threshold in the left ear of 40 dB, whereas the threshold in the right ear was measured at 10 dB. By what factor was the minimum sound intensity heard in the left ear greater than the minimum sound intensity heard in the right ear?A.3B.4C.30D.1000
