How Much Feet Per Second Does Sound Travel?

by | Last updated on January 24, 2024

, , , ,

The speed of through the atmosphere is a constant that depends on the daily temperature. On a standard day at sea level static conditions, the speed of sound is about 760 mph, or

1100 feet/second

. We can use this knowledge to approximately determine how far away a lightning strike has occurred.

How fast does sound travel per foot per second?

speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is

331.29 metres (1,086.9 feet) per second

.

How far does sound travel per second?

In air at a temperature of 70° F (22.2° C), sound travels at a speed of about

1,129 feet (344 meters) per second

, which is roughly equivalent to one-fifth of a mile in one second, or one mile in five seconds (or one kilometer in about three seconds).

How long does it take sound to travel 100 feet?

Feet Per Second Speed Of Sound 90 ft/s 0.079977 sound 100 ft/s

0.088863 sound
200 ft/s 0.177726 sound 300 ft/s 0.266589 sound

Does sound travel at constant speed?


The speed of sound in the atmosphere is a constant that depends on the altitude

, but an aircraft can move through the air at any desired speed. The ratio of the aircraft's speed to the speed of sound affects the forces on the aircraft.

How long does it take for sound to travel 1 mile?

Thunder travels much slower, at the speed of sound, about 1088 feet per second. It takes sound about

5 seconds

to travel one mile.

What is the speed of sound at 5000 ft?

How far does sound travel per millisecond?

Sound travels at a speed of approximately 1130 feet per second. In milliseconds that is

1.13 feet

per millisecond (a millisecond is 0.001 seconds).

How fast is the speed of sound underwater?

Sound travels faster in water than in air. The speed of sound in air under typical conditions is about 343 meters per second, while the speed of sound in water is about

1,480 meters per second

.

What is the 30 30 rule for lightning?

Don't forget the 30-30 rule.

After you see lightning, start counting to 30

. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.

How far away a lightning strike was?

If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning:

5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close

.

How far away is the storm?

After you see a flash of lightning, count the number of seconds until you hear the thunder. (Use the stop watch or count “One-Mississippi, Two-Mississippi, Three-Mississippi,” etc.)

For every 5 seconds the storm is one mile away

. Divide the number of seconds you count by 5 to get the number of miles.

What is the speed of sound at 38 degrees Celsius?

What's the average speed of sound?

On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is

761.2 mph (1,225 km/h)

.

What is the speed of sound at 35000 feet?

At 35,000 feet, the cruising altitude of a typical passenger jet, sound travels at about

660 mph

(1,062 kmph).

Are shock waves faster than sound?

In particular,

shock waves travel faster than sound

, and their speed increases as the amplitude is raised; but the intensity of a shock wave also decreases faster than does that of a sound wave, because some of the energy of the shock wave is expended to heat the medium in which it travels.

Can sound travel through a vacuum?

Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that

they cannot travel through empty space

, where there are no atoms or molecules to vibrate.

How fast does sound travel through concrete?

How long does it take for sound to travel 3 miles?

The speed of sound changes depending on temperature and humidity but one can estimate that sound travels

1 mile in roughly 5 seconds

.

How do you calculate sound distance?

For calculating the distance that sound travels;

distance = velocity x time

.

How fast is Mach 1 at sea level?

The speed of sound (Mach 1) varies with altitude and temperature. If an aircraft is travelling at the speed of sound at sea-level then its speed will be

661 knots

(760 miles per hour) or if it is travelling at the speed of sound at 30,000 feet then its speed will be 589 knots (677 miles per hour).

What is the speed of sound at 85000 feet?

The SR-71 cruised at

Mach 3.2

, more than 2,000 mph, around 85,000 feet.

How far does sound travel in 10ms?

In a typical “room temperature” room, sound travels about 1.12~1.13 feet per millisecond. This will vary with atmospheric temperature and other factors, but your mic(s) would be

a little over 11 feet

from the source(s) if you're going for “10 milliseconds”.

How do you convert feet to milliseconds?


sound travels approximately 1 foot per millisecond

. If you are 10 feet from your speakers, it will take about 10 milliseconds for the sound to reach you.

How is speaker delay calculated?

To calculate the speaker delay,

divide the distance from the sound source by the speed of sound

. This determines the time it takes the sound from the speaker to reach the person.
