Speed Of Sound In Vulcanized Rubber

Solid speed of sound m sec granite 6000 vulcanized rubber at 0 c 54 table 2.

Speed of sound in vulcanized rubber. What is sppeed of sound in volcanised rubber. If the speed of sound is known to be 350 m s what is the wavelength of this note. As a result sound waves travel faster in solids than in liquids and faster in liquids than in gasses. The density of a medium is the second factor that affects the speed of sound.

Frequency f 440 hz wave speed v 350 m s unknown. Pratima bajpai in biermann s handbook of pulp and paper third edition 2018. So it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. For vulcanized rubber the young s modulus y 2 8 10 n m and the density around 920 kg m.

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. So speed of sound 55 1 m sec. Write the equation for wave speed and rearrange it to solve for. 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.

Wave speed the musical note a above middle c has a frequency of 440 hz. Vulcanized rubber is even softer than rubber. Follow report by priyanshuraj90 17 11 2018 log in to add a comment. Wavelength λ.

So the pressure changes in it due to sound waves are not much. While the density of a medium also affects the speed of sound the elastic properties have a greater influence on the wave speed. List the given and unknown values. While not negligible this is not a strong dependence.

The development of the vulcanization process reaction of the carbon double bonds with sulfur to form cross linked chains by goodyear in 1839 led to hard rubber.
