Electroacoustics: Notions of Acoustics

This lecture covers the fundamental concepts of electroacoustics, including frequency response, sensitivity, efficiency, power, intensity, and directivity. It explains the characteristics of electroacoustic systems, transfer functions, and the basics of electrical quantities. The course also introduces the concept of decibel and its application in acoustics. The lecture delves into the analysis of signals, mechanical quantities, and the efficiency of electroacoustic systems. It discusses the importance of frequency in sinusoidal signals and the use of Fourier analysis. Additionally, it explores the impact of noise, harmonic distortion, and dynamic range in electroacoustic systems.
