NEBB S&V CP study guide
NEBB S&V CP · Work through your exam, one topic at a time.
NEBB's Sound and Vibration Measurement (S&V) certification is issued by NEBB, the international certifying association for firms and individuals who deliver high-performance building systems, established in 1971. S&V is one of eight NEBB certification disciplines, and it is offered in two tracks: Sound Measurement and Vibration Measurement. Certification exists at both the firm level and the individual level, and NEBB states that its S&V programs certify firms and individuals that meet criteria established by NEBB. The credential is aimed at two audiences. Topics on this exam: Sound Measurement and Vibration Measurement. The NEBB S&V CP study guide has 2 sections and about 832 words.
01Sound Measurement
The Sound Measurement domain checks whether you can produce a defensible acoustic measurement and a reportable number: correct instrument class, weighting, time constant and bandwidth, calibration traceability, and the arithmetic that turns raw readings into the value compared against a criterion. Items are scenario-based - you are given a setup or a set of readings and asked what is valid, what correction applies, or what the answer is. IEC 61672 / ANSI S1.4 Type 1 tolerance is about ±0.7 dB versus ±1.0 dB for Type 2; Type 1 is expected for design verification and low-level work. Calibrate with an acoustic calibrator, normally 94 dB at 1 kHz, before and after the run; record drift and serial numbers.

The Vibration Measurement domain covers the chain from transducer to reported value: accelerometer selection, mounting, signal conditioning, frequency analysis, unit conversion, and comparison against ISO machinery criteria. Exam items typically give you a sensitivity, a mounting method, or a spectrum setting and ask what the correct result or the limitation is. Piezoelectric accelerometers are specified by sensitivity in mV/g and by mounted resonance. Charge-output types require an external charge amplifier; IEPE/ICP types carry built-in electronics and run on constant current, typically 2–4 mA, with a bias of roughly 8–12 V that must be verified at the connector.
