This means that sound travels 3,916,800 feet per hour. To convert to from ft/hr to mph , simply devide this number by how many feet are in a mile (5,280). This gives us a final answer of 741.818182. Rounding to the nearest ones place gives us an approximate answer: at sea-level, sound travels at about 742 miles per hour.

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.9 s or one mile in 4.7 s.It depends strongly on temperature as well as the medium through which a sound wave is …

With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. Occupational standards specify a maximum allowable daily noise dose, expressed in percentages. For example, a person exposed to 85 dBA per NIOSH or 90 dBA per OSHA over an 8-hour work shift, will reach 100% of their daily noise dose.

by Tim Brice and Todd Hall. The speed of sound depends on several variables, but the only independent variable we need to calculate the speed of sound is the temperature of the air. Enter your air temp and choose your units: The speed of sound: mph. Fahrenheit.

With noise, OSHA's permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. The OSHA standard uses a 5 dBA exchange rate. This means that when the noise level is increased by 5 dBA, the amount of time a person can be exposed to a certain noise level to receive the same dose is cut in half.

The employer shall administer a continuing, effective hearing conservation program, as described in paragraphs (c) through (o) of this section, whenever employee noise exposures equal or exceed an 8-hour time-weighted average sound level (TWA) of 85 decibels measured on the A scale (slow response) or, equivalently, a dose of fifty percent.
