The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.5 feet per second. Notice: The speed of sound changes with temperature and
a little bit with humidity − but not with air pressure (atmospheric pressure).
The words "sound pressure at sea level" are incorrect and misleading.
The temperature indication, however, is absolutely necessary.

Explain the factors that affect the speed of sound?
air, water, glass etc.
What two things affect loudness?
The speed of sound is slower at higher altitudes because the air temperature is lower. The greater the amplitude, the louder the sound. It is your perception of the energy of a sound. What two factors affect the loudness of a sound
What Factors affect the speed of sound wave?
Some factors that affect the speed of sound waves are density of medium, temperature, direction of wind, and humidity. Remember that a sound wave is just a pressure disturbance that travels through a medium by particle interactions. The nature of the medium will affect the sound waves velocity.
How fast is the sound barrier?
I guess you refer to the speed of sound. The speed of sound depends on the material sounds goes through, as well as temperature, pressure, humidity, among others. For example, the speed of sound in air is around 350 meters/second; in some other materials it can be several times as fast.
What factors affect the drag force that acts on high speed train?
Air resistant

Which is faster the speed of sound or the speed of air?
The speed of sound depends on the air factors around it
What are some Factors that affect speed of sound in air?
Think mainly of the temperature and a little bit of the humidity. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

How does the pitch of a sound affect its speed?
Pitch of sound in air does not affect the speed of sound.The speed of sound in air is also not affected by atmospheric pressure.Temperature does affect the speed of sound in air.Similar statements are not true for liquids or solids. It stops being true for gasses when pressure and temperature are near the point that the gas will liquify.
Did pressure greatly affect the peed of sound in the air?
No. Speed of sound is independent of pressure.
How fast is the sound barrier?
I guess you refer to the speed of sound. The speed of sound depends on the material sounds goes through, as well as temperature, pressure, humidity, among others. For example, the speed of sound in air is around 350 meters/second; in some other materials it can be several times as fast.
What will affect the velocity of sound in air?
The speed of sound is dependent on the temperature. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
How does increasing the temperature affect the speed of sound in the air?
Speed of sound increases, when temperature increases. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
In general how does changing the temperature of a medium affect the speed of sound through that medium?
As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in air: V = 331 + 0.59T where T is the air temperature in degrees C.
What is the equivalent estimate to the speed of sound?
The speed of sound is 331 metres per second at zero degree centigrade and at sea level (air pressure and temperature affect the speed of sound).
