2. Someone shouting corresponds to about 88 dB. The area of the opening of the ear is about 1.5 cm. The acoustic impedance of air is 413 kg m- s-1 a. The units of intensity are Watts per square meter (or W/m). Watts are units of power and square meters are an area. This means that I = Power/Area. Given this information, what is the power of the shout? b. What is the pressure amplitude (P) of the sound wave? c. What is the sound pressure level (Lp)?
