Hey everyone, Aleksa here.
Please stay for the read. 📖
There are so many sound baths out there for you to choose from, delivered by individuals with varying degrees of experience, professionalism, and depth of knowledge.
Sati has become known for the quality of our sound-based practices, and that's down to our focus on the science. I am a degree-qualified musician and sound therapist, and Becca, who co-owns Sati, is a biotechnologist and researcher.
Between us, we continue to refine this practice so that you can trust that your investment of time and money is well spent, and not guesswork.
As a trusted voice in the sound therapy space, I feel it's my responsibility to talk about the emergence of novel sound-based practices.
The following is a breakdown about Floating Sound Baths, and why Sati HASN'T jumped on the trend. 👇 👇 👇
Floating sound baths (on airbeds in swimming pools) have emerged as a contemporary extension of immersive sound therapy.
From a physiological acoustics standpoint, it is important to distinguish between experiential immersion (how it feels) and mechanistic efficacy of sound transmission (what it does).
Sound-based practices derive their depth from two primary pathways:
- Airborne auditory perception (mostly heard)
- Mechanically transmitted vibration (felt sound)
In conventional sound bath environments (e.g., indoor rooms with reflective boundaries), both pathways are engaged.
Low-frequency instruments such as gongs and bowls generate complex spectra (a wide spectrum of overtones, frequencies, vibrations) that are partially reinforced by room reflections, extending decay time (duration of sound and vibration) and increasing energy density in the space.
This supports sustained auditory entrainment and, to a lesser extent, body-perceived vibration through structural coupling (floor, mats, frames, 'dry' suspension).
In pool-based floating environments, both of these conditions are altered.
1️⃣ Acoustic field behaviour in open water environments
Water surfaces are acoustically reflective, but they do not provide the geometric containment required for stable reverberant fields. As a result:
- Sound propagation is predominantly hemispherical and outward-dissipating
- Reverberation time is effectively minimal compared to enclosed spaces
- Interference patterns are unstable due to continuous micro-motion of the surface
- Inter-subject variability in sound exposure is high
The outcome is a low-coherence acoustic field, where spatial consistency of stimulus is reduced.
2️⃣ Airbed-mediated mechanical transmission
Participants resting on airbeds are mechanically decoupled from rigid structures. From a physics perspective, this is a system dominated by a compressible air layer with low mechanical impedance matching to the body and negligible coupling to vibrational sources in the environment. The airbed essentially functions as an acoustic dampener in this context.
What this means:
- Low-frequency mechanical vibration (which typically contributes to somatic perception in grounded setups) is significantly attenuated
- The body receives minimal structural vibration input from external sound sources (doesn't FEEL any of it)
- Energy transfer is predominantly via airborne sound to the auditory system, not via tissue conduction (you only HEAR it)
This shifts the sensory weighting toward auditory-only processing, with reduced somatic vibration contribution.
3️⃣ Vestibular and autonomic considerations
Even in still pool conditions, the body is subject to:
- Continuous micro-corrections for balance
- Subtle hydrodynamic movement of the support surface
- Multisensory integration of buoyancy and motion cues
From a neurophysiological perspective, this introduces a mild but persistent vestibular engagement loop, which may reduce the depth of complete postural downregulation typically associated with fully stable support surfaces.
Interpretation:
Taken together, floating sound baths in pools can be characterised as:
- High experiential salience environments (novelty, visual and emotional impact)
- Low structural acoustic control systems (limited reverberation and field stability)
- Predominantly auditory rather than vibro-tactile experiences
- Variable in physiological consistency across participants
This does not negate their value. Subjective relaxation and perceived wellbeing can still be significant.
However, from a mechanistic standpoint, they are better understood as immersive auditory wellness environments with reduced somatic sound coupling, rather than as optimised systems for full-body acoustic entrainment.
In that sense, their primary strength is experiential and contextual, rather than biophysical precision.
I wrote this piece to communicate the mechanisms at play during a sound bath, and help you make informed decisions before purchasing a ticket to the next swimming pool sound bath in your area.
We created our Weightless Woodland Hammock Sound Bath series as a functional alternative to Floating Sound Baths, so we can continue to deliver effective sound therapy while incorporating the sensory reduction that bodily suspension offers. 😊
