# The Ultimate Speed Of Sound List

## Speed of Sound - The Ultimate Speed of Sound List

The speed of sound generally varies based on two parameters. The temperature and density of the medium.

**How temperature affects the speed of sound?**

Heat = more energy. The more energy mediums have the more active the particles are inside. You can see this easily when you boil water. There is so much energy that the water starts turning into vapour. So the more these particles are bouncing around the better they are at transferring sound wave energy.

**How density affects the speed of sound?**

Now you will soon see from that list below that density plays a big role in how efficient the medium is at transferring sound energy. The more particles = short times to collide. Just like newtons cradle below you can see how the energy is transferred very efficiently leaving the middle balls (particles in this example) in the same place.

So now you know what effects the speed of sound let's take a look at the big list below.

Now these haven't been conducted by me and should be taken as a general estimate.

## Speed of Sound in Liquids

Distilled water = 1489 m/sec

Seawater = 1531 m/sec (higher because it is denser)

Glycerol = 1904 m/sec

Mercury = 1450 m/sec

Kerosene = 1324 m/sec

Methyl Alcohol = 1143 m/sec

Carbon Tetrachloride = 926 m/sec

## Speed of Sound in Wood

Ash, along the fiber = 4670 m/sec

Ash, across the rings = 1390 m/sec

Beech, along the fiber = 3340 m/sec

Elm, along the fiber = 4120 m/sec

Maple, along the fiber = 4110 m/sec

Oak, along the fiber = 3950 m/sec

Hardwood = 3962 m/sec

## Speed of Sound in Gas

Hydrogen (O°C) = 1286 m/sec

Helium (O°C) = 972 m/sec

Air (20°C) = 343 m/sec

Air (0°C) = 331 m/sec

## Speed of Sound in Solids

Diamond = 12,000 m/sec

Pyrex Glass = 5640 m/sec

Iron = 5130 m/sec

Aluminium = 5100 m/sec

Beryllium = 12890 m/sec

Brass = 4700 m/sec

Brick = 4176 m/sec

Concrete = 3200 - 3600 m/sec

Copper = 3560 - 4600 m/sec

Cork = 366 - 518 m/sec

Glass = 3962 m/sec

Gold = 3240 m/sec

Granite = 5950 m/sec

Lead = 1158 m/sec

Lucite = 2680 m/sec

Rubber = 40 - 150 m/sec

Silver = 3650 m/sec

Steel = 6100 m/sec

Stainless Steel = 5790 m/sec

Titanium = 6070 m/sec
