Good night, sound sleep is the last thing we hear before falling asleep. But how difficult it is to enjoy that sleep if we always have a hard time falling asleep. Numerous adult finds it hard to fall asleep especially when in school because of the noisy environment and the activities of the brain. However, some noises from this same environment can relax your brain and stimulate better sleep. Since different noises can affect how well we sleep, this article reviews how best sonic hues rid sleep troubles.
WHAT ARE SONIC HUES?
Defining the words separately, sonic simply means the speed of sound in the air while hues are colors. Therefore, sonic hues are a mixture of different frequencies of sounds playing at the same time that can be heard simultaneously at not far away distance.
We can not talk about sound hues without the study of the properties of sound waves.
In physics, waves are disturbances that travel through a medium that enables energy to be transported from its sources to another point without the particles of the medium being transferred between the two points. There are two types of waves differentiated by how the wave is propagated. There are transverse and longitudinal waves.
A transverse wave is the direction of travel of a wave perpendicular(straight) to the direction of the vibration of the medium. An example of a transverse wave is a water wave.
In contrast to transverse waves, a longitudinal wave is one in which the vibration happens in the same direction as the direction of travel of the waves. So, Sound propagates through air as a longitudinal wave, in which the mechanical vibration forming the wave appears along the direction of propagation of the wave.
A longitudinal wave can be created in a winding spring by rolling several of the turns jointly to form a compression and then releasing them to allow the compression to travel the length of the spring.
Therefore, sounds are vibration that propagates as longitudinal and mechanical wave through a medium such as a gas, liquid, or solid. Simply, sound is a type of energy that’s released when an object vibrates.
However, a sound wave consists of alternating compressions and rarefactions. Put another way, regions of high pressure and low pressure, moving at a certain speed.
COMPRESSION AND RAREFACTION
compressions are regions of high air pressure while rarefactions are regions of low air pressure.
Moving on, whenever we talk about a sound wave’s speed, we’re referring to how fast these longitudinal waves move Up…and then down. The technical term is frequency, but many of us know it as pitch. We measure sound frequency in hertz (Hz), which represents cycles-per-second, with faster frequencies creating higher-pitched sounds.
For instance, the Middle C on the piano is measured 261.63 Hz which is a lower pitch, vibrating at a slower frequency.
Note that there is a relationship between wavelength, period, and frequency. This is due to the pressure variation in a sound wave.
Wavelength is the distance covered by the wave after one complete circle and it is measured in meters.
Frequency is the number of complete cycles a wave completes in one second. It is measured in Hertz.
The period is the time for the wave to travel one wavelength. And it is measured in seconds
Moreover, when sound comes into contact with our eardrums, our brains translate the pressure waves into music, or signals we can understand. These impact us negatively or positively over time. An example is the noise sleep aid which impacts us positively.
NOISE SLEEP AIDS.
Noises are prescribed colors on the source of their energy distributed over the different speeds of sound.
Primarily, there have been three different types of sonic hues analyzed with evidence, broadcasting they help one sleep better and decrease the chances of breaking sleep. The following are the types of noises.
1. PINK NOISE.
Pink noise is a background noise we hear in everyday surroundings. It is a soothing sound with each tone having different energy.
According to research, pink noise improved deep sleep and memory in older adults. Also, pink noise reduces brain waves-thus improving a stable sleep. Examples of pink noise include:
White noise is an audible noise spread across all spectrums at the same intensity. Examples of white noise include
1. Buzzing sound by a fan
2. radio stationery
3. humming air conditioner
These noises mask loud sounds that facilitate your brain. That’s why it’s often recommended for sleeping difficulties.
3. BROWN NOISE
Brown noise is a noise with high energy at lower frequencies. Brown noise is deeper and pink and white noise. These include low roaring
strong waterfalls and
In conclusion, Good sleep is of great importance. It makes the body refreshed from depressions, relaxes the brain, and improves concentration.
