What type of meter is typically used for measuring sound levels in an AV environment?

Voltmeter
Ohmmeter
SPL meter
Ammeter

The correct answer is: SPL meter

A Sound Pressure Level (SPL) meter is specifically designed to measure sound levels in decibels (dB), which is crucial in an AV environment where monitoring audio levels is essential for optimal sound quality and compliance with safety standards. SPL meters are highly sensitive and can accurately gauge sound intensity, which helps in evaluating the acoustic performance of spaces, identifying excess noise levels, and ensuring that audio systems function effectively without distortion or excessive volume. In contrast, the other types of meters serve different functions not related to sound measurement. A voltmeter measures electrical potential difference, an ohmmeter measures resistance in electrical circuits, and an ammeter measures the current flowing through a conductor. None of these meters are equipped to assess sound levels or sound quality, which is why they are not suitable for this purpose in an audio-visual context.
