XL2 Analyzer Measures Noise Curves

XL2 Analyzer Measures Noise Curves

The XL2 Analyzer offers with firmware V2.60 on-site measurement of all commonly used noise curves according to ANSI and ISO standards. The XL2 determines the acoustic noise spectrum of a room and displays the results together with the reference curves of the standard selected by the operator.

Noise curve standards are used to objectively rate the noise level and thus the acoustical quality of a room or environment. The XL2 Noise Curve measurements provide numerical and graphical measurement results for Noise Ratings (NR) in accordance with ISO 1996, Noise Criteria (NC) in accordance with ANSI 12.2-2008 and its legacy version of 1995, as well as Preferred Noise Criterion (PNC) and Room Noise Criterion (RNC) curves. The Speech Interference Level (SIL) and Room Criteria (RC) curve rating is also calculated in parallel.

Webinar: Basics of Sound Level Measurements

Webinar: Basics of Sound Level Measurements

NTi Audio cordially invites you to a free live webinar.

The results of sound level measurements are influenced by various physical effects. Therefore, the operator should know and understand the basics of sound propagation, reflection and absorption as well as the meaning of the values obtained and how these values correlate with the human sense of hearing. With this knowledge, measurement errors can be avoided, improving the quality of the measurement results and ensuring their correct interpretation.

On this subject NTi Audio offers an interactive webinar which discusses the theoretical basis and main rules for the practical implementation of sound level measurements. For example, the participants will learn which sound disturbances may occur in closed rooms and what can be done about them, or how to determine the noise exposure of a concert audience.
