How it's made
Source
a bedside patient monitor and the room's air handling. The monitor emits one short pulse per heartbeat from a small piezo speaker (≈ 1 kHz sine with a weak 2nd harmonic); the ventilation is turbulent air in a duct and diffuser, i.e. pink noise; the equipment hum is mains-frequency transformer buzz.
Body
the diffuser band-limits the air to roughly 120 Hz–2.5 kHz with a soft 350 Hz duct body; the hum is a 100 Hz fundamental with 200 and 300 Hz partials, low-passed below 400 Hz; the piezo beep has a faint 2.9 kHz housing resonance riding on its pulse.
Envelope
each beep rises in 6 ms and falls in 50–150 ms (no click); beeps are evenly spaced and the count is rounded so a whole number of beats fills the loop. The air breathes by about ±20 % over drifts.
Variation
beep strength wobbles a few percent; the bed is decorrelated in two channels and the beep sits slightly off-centre. Presets change heart rate, beep level and pitch, ventilation airflow and hum.
