Hearing Loss — types?
Conductive, presbycusis, sensorineural
Sound Pressure Level — definition?
Microscale measurement of sound pressure relative to reference.
Vibration — max displacement?
1.20 mm
Reverberation Time (T₆₀) — meaning?
Time SPL decays by 60 dB in a room.
Wave pressure — formula?
P = A sin(ωt - kx)
Frequency Weightings — purpose?
A-weighting mimics human hearing sensitivity.
Sound Power (Lw) — concept?
Total acoustic energy emitted by a source.
Noise Barriers — primary function?
Reduce sound via reflection, absorption, diffraction.
Vibration Acceleration — formula?
a_peak = ω² x_max; RMS = a_peak/√2.
Hearing Loss Types — examples?
Conductive, sensorineural, presbycusis.
