Sound in Aluminum Sound travels at one of the fastest rates through aluminum, at 6,320 meters per second. This is because aluminum is not particularly dense--meaning that it has little mass in a given volume--and is extremely elastic and capable of changing shape easily.
SteelTherefore the speed of sound is maximum in Steel than other options available.
Solids: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
Some examples of speeds of sound in liquids at atmospheric pressure and T = 300 K are: perfluorohexane, 505 m/s, CCl4, 915 m/s, methanol, 1097 m/s, ethanol, 1139 m/s, cyclohexane, 1244 m/s, toluene, 1298 m/s, mercury, 1448 m/s, water, 1500.7 m/s, and sea water (3.5 mass% salinity), 1537.9 m/s [Kaye and Laby (1986)].

solidsThe speed of sound depends on the medium in which it is transported. Sound travels fastest through solids, slower through liquids and slowest through gases.

Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus sound waves travel much faster in water than they do in air.

Sounds cannot travel through materials like stone, water, and wood . In which medium sound travels fastest: air, water or steel?
An ultrasound is not a unique type of sound, therefore, but is classified differently due to the fact that humans cannot hear it. Ultrasounds have a frequency greater than 20 kHz, which is beyond the frequency limit of sounds that humans are able to hear.

It takes more energy to make large molecules vibrate than it does to make smaller molecules vibrate. Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.

Glass is rigid, and its massiveness is limited by transparency requirements that keep it thin. Glass transmits a lot of sound energy at its resonant frequency and at low frequencies. Laminated glass and insulated glazing units both reduce sound transmission through glass by reducing resonance and adding air-space.
In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators - absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. The total absorption is expressed in Sabins and is useful in, for instance, determining the reverberation time of auditoria.
Sound at 20-200 Hz is called low-frequency sound, while for sound below 20 Hz the term infrasound is used. The hearing becomes gradually less sensitive for decreasing frequency, but despite the general understanding that infrasound is inaudible, humans can perceive infrasound, if the level is sufficiently high.
A dog whistle (also known as silent whistle or Galton's whistle) is a type of whistle that emits sound in the ultrasonic range, which most humans cannot hear but some other animals can, including dogs and domestic cats, and is used in their training. To human ears, a dog whistle makes only a quiet hissing sound.
In the oceans the speed of sound varies between 1,450 and 1,570 metres (about 4,760 to 5,150 feet) per second. It increases about 4.5 metres (about 15 feet) per second per each 1 °C increase in temperature and 1.3 metres (about 4 feet) per second per each 1 psu increase in salinity.
The hardest word to guess in hangman, according to science, is: Jazz. Composed of 75 percent uncommon letters (J and Z) and allowing only three chances at picking correctly, jazz is the perfect storm of Hangman trickery. It's kind of fitting, really. They say jazz is all about the notes they don't play.

A SQL trigger is a database object which fires when an event occurs in a database. We can execute a SQL query that will "do something" in a database when a change occurs on a database table such as a record is inserted or updated or deleted. For example, a trigger can be set on a record insert in a database table.
