Sound waves exist, but with nobody there to perceive said sound, it does not exist I don’t think. We describe sound as two things, sound pressure waves or a noise that we perceived with our ears. One part describes a scientific phenomenon, the other describes the way we perceived that scientific phenomenon. A bit like music. Music is a collection of sound pressure waves. It takes a human to determine that the sound was music. So the short answer is, yes, sound exists. The longer answer is that sound is a thing that living creatures translate from sound pressure waves, so did the sound occur when we create and see our own reality? However the philosophical conversation goes deeper if we think about animals and their hearing, or if the earth hears. Are we looking at this from a human perspective or cosmic perspective and what does those terms even mean to each one of us? Down the rabbit hole we go…
Sounds have waves. The frequency of sound is how close together the sound waves are. The closer together the waves, the higher the frequency or pitch. You can think of this like the beach during a storm, when waves hit the beach more often.
Dogs and people hear about the same at low frequencies of sound (around 20Hz). This changes at high frequencies of sound, where dogs hear up to 70-100kHz, much better than people at only 20kHz. Dogs hear sound frequencies at least three times as high compared to people.
You may have wondered how those special silent dog whistles work? They make high-frequency sounds that dogs can hear but we can’t. Because dogs can hear higher frequencies than us, there are a lot more sounds for dogs to hear.
They can also hear sounds that are softer or farther away, as far as a kilometre. That means dogs can be more sensitive to loud sounds. This is why some dogs are scared of fireworks or thunderstorms. It is also why a dog might bark at a sound you cannot hear.
Sabda (or shabda) is the Sanskrit word for “speech sound.” It sometimes refers generally to electromagnetic waves or vibratory energy. To grammarians, sabda is a unit of language or speech. In Hindu and yogic philosophy, it describes verbal testimony as a way of acquiring knowledge of the Absolute Reality, or Brahman.
In Vedic literature, Shabda Bramhan is said to be omnipresent through the sound of Om (or Aum). Sabda is, therefore, a word expressing a particular meaning manifested by sound. Mantras in Vedic literature depict the spiritual effects of sabda.
Chromotherapy, sometimes called colour therapy or colourology, is an alternative medicine method. It is claimed that a therapist trained in chromotherapy can use colour and light to balance energy wherever our bodies are lacking, be it physical, emotional, spiritual, or mental.
Acoustics is the branch of physics concerned with the study of sound (mechanical waves in gases, liquids, and solids). A scientist who works in the field of acoustics is an acoustician. Acoustics is the science concerned with the production, control, transmission, reception, and effects of sound.
Sound bath is an ancient sound-healing practice whereby the yogi relaxes in a reclining position – often supported in savasana (corpse pose) – and allows the healing sounds of traditional musical performances to bath over him/her. The music is typically generated by such instruments and methods as singing bowls, gongs, drumming, tuning forks and chanting.
Sound bath is an ancient practice dating back more than 2,000 years with roots in Tibet. It has recently gained popularity in the West as a relaxation technique in conjunction with yoga and meditation.
In Hinduism and yogic philosophy, para nada is the highest of the four levels of sound in the universe. The term comes from the Sanskrit, para, meaning “highest,” “ultimate” or “supreme”; and nada, meaning “sound” or “tone.”
Para nada is transcendental sound that is beyond hearing or the mind’s understanding and is infinite. Associated with the cosmic vibration of Om, para nada is heard only when the yogi is in a state of higher consciousness, just before experiencing samadhi, the final limb of yoga.
While the Upanishads say that para nada is manifested in Om, it is a silent Om. According to some Hindu texts, para nada has no vibration, movement or frequency but is a sound only enlightened yogis can hear. It is sound at its maximum pitch.
The other three levels of nada are:
Vaikhari ~ This is sound that is audible to the human ear. Madhyama ~ This sound is heard in the mind. Pashyanti ~ This is a sound that is perceived visually.
Believing that the whole universe is composed of sound vibrations, Nada yoga focuses on transformation from within through sound. The goal is to hear the ultimate sound, or para nada.
In Hinduism and yogic philosophy, the cosmic sound is the auditory manifestation of Brahman, the Absolute Truth or Ultimate Reality. It is verbalized as the mantra, Om (also spelled Aum). According to the Bhagavad Gita, “God is the sound of Om.”
The cosmic sound is associated with the creation of the universe. It is believed that before creation, the humming of energy existed. That energy became the vibration of creation and so the universe was created out of the ever-present sound of Om. This cosmic sound and its vibration still exists around and inside everyone.
