Sound can be defined as vibrations that travel through the air or another form of medium
that can be heard when they reach the vicinity of the hearing range of a person’s or animal’s ear.
Liquid, on the other hand, is a substance that flows freely but has constant volume and has
consistency, for example, oil or water (Guyot et al., 2017). Sound and liquid can be termed to be
different in more ways than they are similar; however, similarities between sound and liquid are
From a scientific point of view, both sound and liquid can be expressed in terms of
waves. Sound is classified as a longitudinal wave and while being transmitted through liquids,
gases, and plasma. Longitudinal waves can also be referred to as compression waves. Sound
requires a medium of propagation to be transmitted. However, through solids, sound can be
transmitted in both forms of longitudinal and transverse waves. Under normal conditions, sound
travels at a speed of 343m/s. On the other hand, liquids can also support waves, though only at
short wavelengths (Safarov et al., 2018). Liquids, specifical water, have visible waves, unlike
sound waves. Water waves can be explained in factual natural version or a scientific-physicist
Water waves can be observed in water bodies such as oceans, seas as well as small water
bodies. That is the natural phenomenon type of waves that are generated by the forces of nature.

However, in comparison with sound waves, there an induced scientific kind of water wave that is
similar to sound waves (Guyot et al., 2017). A ripple tank induces these types of waves. These
waves are subject to many experimental variations identical to sound waves. Both liquid waves
and sound waves are subject to interference. These waves experience a particular type of
phenomenon called diffraction. This conceptual phenomenon can be proved using a double-slit
experiment. Interference of both sound and liquid waves can be constructive or destructive
(Safarov et al., 2018). Constructive interference is when the resultant wave is larger than the
original wave, while destructive interference occurs when there is the interaction of two waves
with the same amplitude and instead of the formation of a crest, there is a cancellation.
Another definition of sound when the word is classified as an adjective means solid. With
this frame of reference, of having sound like a solid, many similarities can be derived from the
topic of similarities between sound and liquid. Framing sound to be a solid will sound in a better
position to have similarities with liquids (Safarov et al., 2018). Both sound and liquid can be
identified as states of matter, a scientific explanation. This means that they both have volume and
shape. This is a definitive aspect of all forms of matter. These characteristics are evident in solids
have definite shape and volume while liquids have definite volume and indefinite shape. Sound
and liquids can be defined to have molecules. In sound, molecules are packed carefully together
hence being entirely compact (Guyot et al., 2017). In liquids, molecules take the shape of the
container in which they are poured into. Sound and liquid can, therefore, be depicted to have
atoms in their states of matter.
There can be an infusion of both sound and liquid. Liquids produce sound in the form of
splashes of waves. The sound from a splash is considered to be associated with acoustic
multipoles of all types, mostly being simple sources, dipoles, and quadrupoles. This shows the
relation between sound and liquid. Also, both sound and liquids are affected by temperature. The
speed of sound is affected by the temperature of the surrounding (Safarov et al., 2018). When
there is high temperature, the speed of sound is faster due to more energy and speedier vibration
of particles. Liquids are also affected by heat since when the temperature of liquids is raised,
they become hot and vice-versa for the numbing effect. This is a fact that depicts a similarity
between sound and liquid.
