Select the correct answer from each drop-down menu. The decibel level of a normal conversation, which has an intensity of 3.2x10-6 watts/m2, is (ANSWER1) dB. If the decibel level goes up to

80, the intensity of the sound will be

(ANSWER2) watts/m2

B = 10103(t.), where is the sound level in decibels, is the intensity of sound you are measuring, and I is the

Use the formula

smallest sound intensity that can be heard by the human ear (roughly equal to 1x10-12 watts/m2).

The intensity of sound in decibel is 65 dB

The intensity of sound in Watts/m² is 1 x 10⁻⁴ W/m²

Step-by-step explanation:

The intensity of sound in decibel is given by;

where;

I₀ is the smallest sound intensity that can be heard by the human ear = 1 x 10⁻¹² watts/m²

= 65 dB

If the decibel level goes up to 80 dB, the intensity in W/m² is given by;
