Nothing!! It remains same. In a closed room, if it is long enough, you may experience an echo. That is reflection of sound. But speed of sound does not change.
The speed of sound at room temperature (around 20 degrees Celsius) is approximately 343 meters per second in air. The speed varies depending on the medium through which sound is traveling, with sound traveling faster in denser materials.
The speed of sound in a gas depends on factors like temperature and pressure. In general, the speed of sound in air at room temperature is about 343 meters per second.
The formula for the frequency of sound is: frequency = speed of sound / wavelength. The speed of sound in air is approximately 343 meters per second at room temperature.
Isaac Newton calculated the speed of sound in air at room temperature to be around 343 meters per second.
In dry air, at 20°C, the speed of sound is 343 meters/second.
The speed of sound measured at sea level is 661.47 knots.
Sound is not audibly louder in a room with the door open or closed. If I had a volume meter I might be able to measure the sound being slightly louder with it closed because the sound would reflect off a closed door but leave through an open one, but you'll never hear it. I determined this experimentally. First I closed the door to the room and played some Iron Maiden with my speakers turned up halfway. Then I opened the door to the room and played the same song at the same volume setting. It didn't get any quieter in there. The real effect, of course, is OUTSIDE the room. If I open the door and play Maiden, the neighbors hear it better than if I keep it closed and play them.
Well speed of sound in air at room temperature is 350 m/s . It depends on the density of the medium. Sound cannot propagate through vacuum. Speed of sound is directly proportional to the temperature of the medium.
The speed of sound in water vapor is approximately 330 meters per second at room temperature. This speed can vary depending on the temperature and pressure of the vapor.
Be it a big or small room.. if the environmental conditions in both the room are same, speed of sound will also be same.... Speed of sound depends on the density of the air present in the room.. More the density more will be the speed of sound.. and vice versa...
The speed of sound in air at room temperature is 350 m/s. At 21 C it is 343.6 m/s
The speed of sound in air at 20°C is 343 m/s.
