The speed of sound is 340.29 m / s at sea level, on air. Lets call that X Since X is in meters per second, you can multiply by 60*60= 3600, which is the amount of seconds in a hour this would leave : X*3600 = 340.29 * 3600 = 1225044 m/h you can di...

Here's an example: OSHA allows 8 hours of exposure to 90 dBA but only 2 hours of exposure to 100 dBA sound levels. NIOSH would recommend limiting the 8 hour exposure to less than 85 dBA. At 100 dBA, NIOSH recommends less than 15 minutes of exposure per day.

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.

I see that many people have already answered. So I will just add one further thought (in case it is of interest): You use the "speed of sound in air" whenever you estimate the distance to a thunderstorm by the time difference between seeing the fl...

https://en.wikipedia.org/wiki/Speed_of_sound
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 (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.It depends strongly on temperature as well as the medium through which a sound wave is propagating.

Each line by itself represents 100% of the allowable noise dose per 24-hour day. In other words, if you've already experienced 15 minutes at 100 dBA, you're "done for the day," and the remainder of your 24-hour period should have NO exposure above 85 dBA, and preferably should be below 70 dBA.
