Speed Of Sound In Vulcanized Rubber

So the pressure changes in it due to sound waves are not much.

Speed of sound in vulcanized rubber.

List the given and unknown values. While not negligible this is not a strong dependence. Wave speed the musical note a above middle c has a frequency of 440 hz. Liquids liquids temperature c density kg m 3 adiabatic bulk modulus pa ratio of specific heats speed of sound m sec water fresh 20 998 2 18 10 9 1 004 1481 water sea 13 1026 2 28 10 9 1 01 1500 mercury 20 13 600 25 3 10 9 1 13 1450 table 3.

So it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. Vulcanized rubber is even softer than rubber. At 0 oc the speed of sound is 331 m s whereas at 20 oc it is 343 m s less than a 4 increase. The density of a medium is the second factor that affects the speed of sound.

One of the earliest industrial developments was the use of natural soft rubber poly cis isoprene in the early 1800s. So speed of sound 55 1 m sec. Frequency f 440 hz wave speed v 350 m s unknown. As a result sound waves travel faster in solids than in liquids and faster in liquids than in gasses.

If the speed of sound is known to be 350 m s what is the wavelength of this note. Ask for details. While the density of a medium also affects the speed of sound the elastic properties have a greater influence on the wave speed. Solid speed of sound m sec granite 6000 vulcanized rubber at 0 c 54 table 2.

What is sppeed of sound in volcanised rubber. For vulcanized rubber the young s modulus y 2 8 10 n m and the density around 920 kg m. Follow report by priyanshuraj90 17 11 2018 log in to add a comment. The silicone rubber doped with yb2o3 powder showed a sound speed of 0 88 km s an acoustic impedance of 1 35 x 10 6 kg m2s an acoustic attenuation of 0 93 db mmmhz and a shore a hardness of 55.
