Data obtained conforms to IEC 60711-1981 (similar to the modern day IEC 60318-4 measurement standard), ANSI S3.25-1979 (R 1986), and ITU-T Rec. P 57 (Type 2). Additional testing out to 50 kHz is not shown for ease of interpretation. Sound pressure level is expressed as a differential and normalized to 500 Hz. The plot is not necessarily indicative of final product performance and has been generated solely for informational purposes.
