Introduction to Acoustic and Audio System Engineering

Introduction

The auditory sense is the primary means through which humans experience sound. Devices engineered to interface with this sense—whether they generate, modify, or transmit sound—have a profound impact on our daily lives. This article aims to provide a comprehensive overview of the intricacies involved in auditory devices and technologies, segmented into three critical areas:

• Acoustic Properties: This section will delve into the fundamental aspects of acoustic waves. We'll discuss their propagation characteristics and examine the metrics used in the industry to quantify sound quality.

• Audio Hardware and Processing Techniques: Here, we'll introduce a variety of hardware devices responsible for generating and recording acoustic waves. We'll also explore the techniques used for audio signal processing.

• Audio Interfaces: In the final section, we'll focus on the interfaces that facilitate the transfer of audio data. This will cover both internal interfaces within a processing board and external interfaces, such as those connecting to an audio sound system.
