Classification
Nouns denoting natural phenomena.
Examples
- The instantaneous sound pressure at a point in the sound field was measured to be 10 pascals above the average pressure.
- The microphone was designed to capture the instantaneous sound pressure fluctuations in the acoustic signal.
- Researchers studied the instantaneous sound pressure variations in the vicinity of the sound source to understand the sound propagation patterns.
- The instantaneous sound pressure at the listener's ear was affected by the reflections from the surrounding surfaces.
- The sound level meter was calibrated to measure the instantaneous sound pressure levels in decibels.
