Precision Integrating Sound Level Meter
Information
Precision Integrating Sound Level Meter Type 2236 is a Type
1 sound Level Meter complying with ANSI S 1.4-1983 and
Draft S 1.43, 6th Sept., 1992, and EEC 651 (1979) and 804
(1985). It can measure the following parameters:
• Maxi/, maximum SPL since the last reset
• MinL: minimum SPL since the last reset
• MaxP: maximum Peak level since the last reset
• Peak: maximum Peak level in Is interval
• SPL: maximum EMS level in Is interval (according to DEC 651)
- Leq: equivalent continuous sound level (Leo according to
IEC 804)
- Llm: equivalent continuous impulse sound level (if time
weighting is I) (Lfcn according to IEC 804, Appendix B)
• LAV4: equivalent continuous sound level with Exchange Rate
of 4dB (LAV,4 according to ANSI S 1.25)
- LAV5: equivalent continuous sound level with Exchange Rate
of 5dB (L^y^ according to ANSI S 1.25, Lqska)*
- SEL: Sound Exposure Level (if A-weighted, then = Lg^,
according to IEC 804)
- IEL: Impulse Sound Exposure Level (if time weighting
is I)
- LEPd: Daily Personal Noise Exposure Level (see section
8.3)*
- LN (3) (default L90): RMS level exceeded Ns% of the
measurement time (L^)
• LN (2) (default L5q): RMS level exceeded N2% of the
measurement time (Lj^)**
- LN (1) (default L10): RMS level exceeded N]_% of the
measurement time (L^)**
- Ovl: Input signal overloading instrument (% of the
measurement time)
In addition, Precision Integrating Sound Level Meter Types
2236 C—007 and 2236 D—007 contain Vi-octave Filter sets
between 31.5 Hz and 8 kHz which comply with ANSI S 1.11-1386
and IEC 225 (1966). They can measure all the above-mentioned
parameters in each of the Filter bands.
