ANSI Standards

Definition

ANSI Standards refer to the guidelines set by the American National Standards Institute that provide a framework for consistency and safety in various industries, including noise control engineering. These standards help ensure that sound measurements, instruments, and noise control technologies are reliable and uniform across different applications, allowing for effective communication and compliance in environmental noise assessments and engineering solutions.

5 Must Know Facts For Your Next Test
