UNIT I FUNDAMENTAL OF ACOUSTICS 9
Acoustics waves – Linear wave equation – sound in fluids – Harmonic plane waves –
Energy density – Acoustics intensity – Specific acoustic impedance – spherical waves –
Describer scales-Transmission from one fluid to another normal and oblique incidence –
method of images-
UNIT II RADIATION AND RECEPTION 9
Radiation from a pulsating sphere – Acoustic reciprocity – continuous line source -
radiation impedance - Fundamental properties of transducers- Absorption from viscosity
– complex sound speed and absorption – classical absorption coefficient
UNIT III HEARING & SPEECH- PIPES RESONATORS AND FILTERS 9
Physiology of speech and hearing- fundamental properties of hearing – loudness level
and loudness – pitch and frequency – voice- Noise- spectrum level and band level –
combing band levels and tones – detecting signals in noise – detection threshold -
Resonance in pipes - standing wave pattern absorption of sound in pipes – long
wavelength limit – Helmoltz resonator - acoustic impedance - reflection and transmission
of waves in pipe - acoustic filters – low pass- high pass and band pass.
