Sound goes far beyond what we hear. Vibrations, frequencies, and music interact with the body in surprising ways. Discover what science already knows and how this knowledge opens new possibilities for Sound Branding and experience design.

How do sound and music influence our bodies and emotions?

Imagine a piece of music that makes your body relax, a low frequency you feel before you even realize you are hearing it, or a melody that completely changes the atmosphere of a room. Sound has the ability to cut across human experience. It reaches the ears, stirs emotions, evokes memories, and also triggers physical responses.

This is not just a poetic perception. Science has spent decades investigating how vibrations and mechanical stimuli interact with cells, tissues, and the nervous system. And some findings are especially interesting for those who work with music, environments, and sound experiences.

One of them has a name: mechanotransduction. It is the process by which cells convert mechanical stimuli, such as pressure, movement, and vibration, into biological responses. In other words, our bodies do not just hear the world: they also respond to it physically.

The body also listens: the invisible music of cells

With every step, movement, or muscle contraction, our body produces and receives mechanical stimuli. Cells have structures capable of sensing these forces and converting them into biological signals.

Researcher Donald Ingber, founder of Harvard’s Wyss Institute, has devoted a significant part of his career to investigating precisely this relationship. His studies show how physical forces participate in the regulation of cell behavior, alongside chemical and genetic factors.

It is a fascinating perspective: life is also movement. And cells have mechanisms to sense and respond to that movement.

The Nobel that revealed pressure sensors in the body

In 2021, the Nobel Prize in Physiology or Medicine recognized the discoveries of David Julius and Ardem Patapoutian on receptors for temperature and touch.

Patapoutian’s work identified the ion channels Piezo1 and Piezo2, proteins that function as mechanical sensors. They allow certain cells to perceive physical forces and convert those stimuli into electrical signals.

Piezo2, for example, plays a fundamental role in touch and proprioception, our ability to perceive the position and movement of our own body. Piezo1 participates in the perception of blood flow.

These discoveries expanded the understanding of how the body transforms physical stimuli into biological information. And they help explain why the relationship between vibration and the body attracts so much scientific interest.

When vibration meets bone

One of the most well-established fields of research on vibration and human tissue is the study of bones.

Biomedical engineer Clinton Rubin, of Stony Brook University, has spent decades investigating how low-intensity mechanical stimuli can influence bone structure.

In a study published in the journal Nature in 2001, researchers observed the effect of low-magnitude, high-frequency vibrations on adult sheep. After a year of daily stimuli, the group exposed to vibration showed a 34.2% increase in trabecular bone density of the proximal femur compared to the control group.

Other studies have also investigated the effects of whole-body vibration in humans, including young women with low bone density.

But there is an important distinction: these experiments used vibrating platforms, not music. Although 30 Hz falls within the range of deep bass, the stimulus studied was transmitted mechanically through the equipment’s support surface.

The finding is interesting precisely because it shows that certain vibrations, under specific conditions, can participate in biological processes.

Ultrasound: when sound enters medicine

Ultrasound is another demonstration of how sound waves can go beyond the limits of hearing and find applications in the human body.

In medicine, ultrasound is already used in imaging and in various therapeutic procedures. One of the investigated applications was low-intensity pulsed ultrasound, known as LIPUS, initially studied as an aid in fracture healing.

Early results raised expectations. However, a large clinical trial published in the BMJ in 2016, involving 501 patients with tibial fractures, found no significant differences in healing or functional recovery between patients who received the treatment and those who used a sham device.

The episode carries an important lesson: not every promising laboratory finding automatically translates into clinical benefit. Science needs to test, compare, and validate results before recommending an application.

Music, vibration, and well-being: what do we know about vibroacoustic therapy?

Here the conversation moves even closer to the musical universe.

Vibroacoustic therapy combines music, low-frequency sound vibrations, and therapeutic guidance. Developed from the experiments of Norwegian researcher Olav Skille in the 1980s, this approach has been investigated in studies related to pain, rehabilitation, and well-being.

A review published in BMJ Open in 2022 analyzed research on the use of vibroacoustic therapy for pain management in adults. Among the studies examined, the frequency of 40 Hz appeared most often, and sessions generally lasted between 20 and 45 minutes.

The results spark interest, but important differences remain between the methods used. Frequency, intensity, duration, and mode of application vary considerably, making comparisons and definitive conclusions difficult.

The field continues to develop. And it is worth remembering: investigating the therapeutic effects of specific vibrations is one thing; claiming that listening to music alone produces the same results is another.

What does all of this have to do with Sound Branding?

Perhaps one of the most interesting ideas from this scientific investigation is realizing that the sound experience is not limited to the ear.

When we enter a space, hear a piece of music, recognize a voice, or identify a brand’s sonic signature, our brain and body both participate in that experience. Rhythm, frequency, timbre, intensity, melody, and harmony all help shape how we perceive an environment and relate to it.

It is precisely in this territory that Sound Branding becomes relevant. Creating a sonic identity goes far beyond choosing pleasant music or producing a sound logo. It means building a language capable of translating a brand’s personality into experiences that can be recognized, remembered, and felt.

A soundtrack can transform the atmosphere of a store. A soundscape can make a space more welcoming. A voice can bring a company closer to people. A melody can create recognition and stir emotional associations.

We are not saying that a brand can regenerate tissues or produce therapeutic effects through its music. Those are different questions and require specific evidence. But understanding that sound participates in the human sensory experience opens extraordinary possibilities for designing more meaningful relationships between people, brands, and environments.

Sound is not just what we hear. It is also what we feel, recognize, and carry with us.

At Zanna Sound, we believe in the power of sound to transform experiences and build more meaningful connections between brands and people. Because a brand can also be heard, felt, and remembered.
