- 2 Q:A- Calculate the sound level in dB of a sound intensity 10-8 Wm-A noise has an intensity of 2.4×10-8 W/m2. If the threshold of human hearing is I0 = 1.0×10-12 W/m2, calculate the sound intensity level in dB. Use two digits of precision for your answer.12 gives the loudness of sound L (in dB) based on the intensity of sound I (in W/m²). The value I = 10 The formula L=10 log threshold for hearing for midfrequency sounds. Hearing impairment is often measured according to the minimal sound level (in dB) detected by an individual for sounds at various frequencies. For one frequency, the table depicts the level of hearing impairment. Category Mild Moderate Moderately severe Severe Profound Loudness (dB) 26≤L≤40 41≤L≤55 56≤L≤70 71 ≤L≤90 L>90 W/m is the minimal (a) If the minimum intensity heard by an individual is 9421.4 x 108 W/m², determine if the individual has a hearing impairment. Round to the nearest tenth. (b) If the minimum loudness of sound detected by an individual is 40 dB, determine the corresponding intensity of sound.
- Use the data in Table 3 to make this plot. That is plot I, on the -axis vs. (1/d^2), on the x-axis. Then draw a best fit line throught the data points.Loudness (L), in decibles (dB), of a sound of intensity I is defined to be L=10log( I/I0), where I0=10-12(W/M2) (watts per meter square) is the minimum intensity detectable by the human ear. A.) Find the loudness L, in decibles (dB), of a trombone given the intensity is 1010I0 B.) Find the intensity of a rock concert whose loudness is 115 decibles. C.)

- Sound waves travel at roughly 340 m/s at room temperature. The minimum hearing range of a human is 20Hz. a) What is the wavelength of this wave? b) Could this wavelength fit inside the dimensions of Room 411( room dimensions are roughly 11.5 m x 8.7 m)? Justify your answer with sound reasoningProblem #3: What intensity level dB in does a sound of 3. 04 × 10–4 W/m2 correspond to?The intensity of a sound is 400 W/m2 If the intesity level of sound decreased by 10 decibels, what is the new observed intensity?
