Everyone wants to listen to their brain, but ultimately, they listen to their heart. The brain acts as the logical solution to any problem we face, as it can process and interpret all the sensory information we are bombarded with every day.
Sound is one of the many senses we require along with the other senses; while some do not have the luck to be auditory blessed, rest neglect the privilege they have. Out of the powerful senses, audio-visual sound has its own importance as it can evoke emotions, trigger memories, and even improve our physical well-being. Discover how sound influences many aspects of your daily life and how it plays a significant role in upscaling your lifestyle.
Defining acoustics
Everything in today’s world is bound to have a scientific meaning, although some remain undiscovered. But sound leads us to the deep physics of sound waves via different mediums.
Sound waves are typically created when objects vibrate, disrupting the surrounding air particles. These vibrations usually travel as waves, reaching our ears and causing our eardrums to vibrate.
The big three
Sound waves can be characterized by many properties, such as frequency, wavelength, and amplitude. Firstly, frequency refers to the number of wave cycles within a specific period, which further determines pitch in sound waves, measured in Hertz. At the same time, wavelength means the distance between consecutive wave peaks or troughs, and amplitude means the maximum displacement from equilibrium, which governs sound intensity or loudness, measured in decibels.
Brain processes sound
Once sound waves reach our ears, they are usually converted into electrical signals by specialized cells called hair cells in the inner part of the ear, as these hair cells are susceptible and may detect even the slightest vibrations caused by sound waves. Once the electrical signals are generated, they travel through the auditory nerve to the brain later.
After reaching the brain, the electrical signals are processed and interpreted in the auditory cortex. This part of the brain analyzes various aspects of sound, including pitch and timbre.
Psychological impact
Sound has a deep connection with emotions as it evokes emotional responses like happiness, caution, rage, etc. Specific sounds elicit specific responses. For example, the cheerful tune can evoke the emotion of joy and happiness, while the soft sound of waves crashing through the bay can create a calm vibe overall.
Sudden loud noises or eery music can trigger feelings of fear and anxiety. For example, multiple car horns going off during traffic can cause irritation, while a jarring alarm tone can immediately alert you.
Many sounds decide whether you are the prey or the predator, where you are supposed to be wary, and where you are supposed to stay, making our brains attuned to the different sounds we experience daily, signalling fear or safety further evoke the correct response in us.
Moreover, the impact of sound is not limited to biological factors but can also be influenced by cultures. For example, listening to different genres, with specific elements depicting the original tradition, can make you associate with specific emotions and how we react to them.
The vitality of sound in memory and learning
It is a human instinct since you are born to observe different sounds and elicit the correct response. This is mainly why infants are trained with auditory lessons and phonics.
The essential link between sound and memory is evident in our daily activities. For example, we often find it easier to memorize information given to us, such as essential topics from a chemistry chapter, melodically or rhythmically. Think about how catchy jingles from advertisements or song lyrics can help us effortlessly recall product names or phone numbers. They slip off our tongues smoothly and, well, subconsciously.
Various researchers have conducted studies and explored sound’s impact on memory and learning, revealing intriguing findings. For example, background music or specific auditory cues can improve memory recall and concentration. This is usually known as the “Mozart effect,” which became famous after a study recommended that listening to Mozart’s music can temporarily boost spatial-temporal reasoning skills, like job application aptitude tests. While the exact reasoning behind this effect is unknown, it shows the excellent influence of sound on our cognitive abilities.
Sound also helps enhance our multisensory experience, which can improve our learning abilities and widen the scope for better information retention. For example, taking information via multiple senses, like watching a show on television, heightens our audio-visual aspect and helps us remember and understand information easily.
Physiological impact of sound
Beyond the specific factors, it majorly affects the whole human in whole. Likewise, sound frequency and noise pollution can significantly influence our health and well-being.
Prolonged exposure to high and loud noise, such as loud traffic or industrial machinery, can lead to hearing loss, stress, and sleep disturbances. Additionally, low and minimal noise, like loud transportation or building activities, can cause annoyance, cardiovascular issues, and even affect cognitive activities. Noise pollution disrupts our physiological and psychological equilibrium, contributing to various health issues and degrading the overall quality of a good lifestyle. Mitigating noise pollution through proper urban planning, noise regulations, and personal measures is a step toward a promising future and promotes well-being.
Interestingly, many meditation techniques involve sound as a form of therapy in many places worldwide. Sound therapy, also known as vibrational therapy, has been implemented by many as it uses certain sound frequencies to produce calm and peaceful sounds that heighten your senses and target different parts of your body therapeutically.
Music therapy
One of the many agreed forms of sound therapy involves music, as it improves mental and physical health and overall well-being.
This type of therapy mainly involves
listening to music
singing and vibing along
meditating
playing an instrument
With a history of this particular phenomenon working in ancient Greece, it evolved to various other nations experimenting with it to cure mental illnesses, boost morale in the military, help people work faster during their daily activities and more productively, and even help you ward off evil spirits by chanting.
The profound treatment
It has mainly been used to treat many issues, like
anxiety disorders
depression
post-traumatic stress disorder
dementia
autism
behavioural disorders
cancer
The key instruments
Along with voice, these different instruments used help in successful music therapy:
singing bowls
tuning forks
pan flute
harp
drums
Some methods use many instruments in one session, such as a guitar, piano, or other instrument.
Conclusion
Sound therapy might seem mundane, but many youngsters religiously worship Spotify and other audio-streaming platforms. It might seem like a mere factor, but sound therapy has overall changed many people’s lives, especially if they are diagnosed with certain conditions. Therefore, the role of sound therapy is not luddite but a broad topic to be well-versed on, especially with its multiple benefits.
