You more than likely remember from your science classes in institution that the rate of sound is a constant. However, that constant speed is no necessarily the speed at i m sorry the sound get you. The product which sound is transferred through need to be taken into consideration.

You are watching: What medium does sound travel fastest through

For example, exactly how does density affect the speed of sound? because sound tide involve the deliver of kinetic power between adjacent molecules, the closer those molecules space to every other, the faster the sound travels. Therefore, sound travel much much faster through solids than v liquids or gas. When knowledge the speed of sound through various mediums or materials, there are several determinants to consider besides density.

1. Elastic Properties

Elastic properties are the nature of a material that permit it to keep its shape once you use force come it. Products with higher elastic properties go back to their normal shape faster, making it less complicated for sound to travel through them. That’s why sound travel much faster through lead, for example, than rubber, which has really low elastic properties.

2. Waiting Density

Just as solid objects enable sound come travel much faster than less thick ones, the thickness of gasses affect how quickly sound travels, together well. For example, sound will travel faster in hydrogen than regular air due to the fact that it is a much denser gas. You’d mean sound to travel faster in cooler air than hotter air, because colder waiting is denser. However, this isn’t the case, because that the reason declared below.

3. Temperature

Why go sound travel much faster at higher temperatures than cooler ones? when air is colder, the molecules room closer together, for this reason sound transmission should be easier. This is true the solids and liquids, however gases law a small differently. Once gases warmth up, your molecules relocate much much more quickly. This boosted vibration transmits the sound an ext quickly 보다 it would in colder, but an ext static, air.

A perform of The rate of Sound Through various Materials

In case you’re curious just how easily sound travels through various mediums, here are a couple of of the different materials and also how quick sound moves through them:

Rubber — 60 m/sAir at 32 levels — 331 m/sAir in ~ 68 levels — 343 m/sAir in ~ 104 levels — 355 m/sLead — 1210 m/sGold — 3240 m/sGlass — 4540 m/sCopper — 4600 m/s

Understanding the way sound travels through different mediums is crucial part of exactly how we in ~ Soundproof Cow develop our sound blocking and also sound absorbing materials. To learn much more about just how Soundproof Cow assets can block undesirable sound and absorb harsh noises, visit
