Purpose
Sound studied through vibration, wave propagation, resonance, impedance, hearing and the interaction of sources with spaces and materials.

Entities → interactions → mechanisms → scales → measurement
Follow vibration from source to medium to receiver.
Acoustics links mechanical vibration to wave fields and perception, making boundaries, geometry and frequency response central to what is heard and measured.
Wave propagation
Track speed, wavelength, attenuation and superposition through gases, liquids and solids.
Resonance & modes
Study standing waves and natural frequencies in strings, cavities, structures and coupled systems.
Impedance & boundaries
Explain reflection, transmission and absorption through mismatches at interfaces.
Hearing & rooms
Connect physical spectra and reverberation to auditory perception without treating perceptual response as a simple copy of pressure level.
Keep the boundaries visible.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
frequency ≠ pitch
amplitude ≠ loudness
absorption ≠ sound isolation
Questions that organize the Side.
Use these to test whether the model is becoming explanatory rather than merely familiar.
How do geometry and boundary conditions determine acoustic modes?
When can sound be treated as rays rather than waves?
Which measured acoustic quantities predict perception reliably, and where do they diverge?
What should carry weight here?
Use calibrated pressure and vibration measurements, explicit geometry and material properties, and psychoacoustic evidence when claims concern perception.
