SV 102A+ Class 1 Dual-Channel Noise Dosimeter
The SV 102A+ is the higher-performance choice for professional occupational-noise and acoustic consultants who need Class 1 accuracy, dual-channel measurement and advanced MIRE capability. It is designed for complex exposure conditions where noise differs between the ears, or where a headset/ear measurement must be compared with a shoulder or reference measurement.
Key features
What the SV 102A+ has
- Two independent measurement channels for left/right measurements or headset/reference measurements at the same time.
- Class 1 sound-level-meter performance under IEC 61672.
- Wider 20 Hz–20 kHz frequency coverage for demanding acoustic investigations.
- MIRE capability using the optional SV 25S in-ear microphone, including ISO 11904-1 workflows.
- High 48 kHz sampling for preserving close-to-ear transients and high-frequency content.
- 1/3-octave analysis for MIRE and detailed diagnostics, plus 1/1-octave analysis for hearing-protector investigations where configured.
- Audio recording for source verification and post-measurement investigation.
- Occupational exposure results including dose, TWA and LEX,8h/LEP,d, subject to the selected measurement profile.
What the SV 102A+ adds over SV 102+
- Class 1 accuracy instead of the SV 102+ Class 2 platform.
- Wider frequency coverage and higher-speed sampling for more demanding acoustic work.
- Stronger support for specialist MIRE, headset, helmet and close-to-ear investigations.
- More detailed frequency and audio analysis options for consultancy reporting and source investigation.
SV 102A+ or SV 102+?
| Requirement | Choose |
|---|---|
| Routine occupational noise dosimetry and budget-conscious dual-channel work | SV 102+ |
| Class 1 accuracy or a Class 1 sound-level-meter function | SV 102A+ |
| MIRE under headsets, helmets or close-to-ear sources | Either; choose SV 102A+ for the more demanding work |
| Left/right or headset/reference measurements | Either; both are dual-channel |
| High-frequency or detailed acoustic investigation | SV 102A+ |
What it solves
It helps teams distinguish routine Class 2 dosimetry from projects that require Class 1 accuracy or specialist close-to-ear analysis.
Applications
- Advanced occupational noise exposure assessment
- Industrial hygiene consultancy and hearing-conservation programmes
- Headset, call-centre, aviation and military noise studies
- Complex or asymmetric exposure investigations
- MIRE measurements requiring detailed frequency analysis
