Acoustics. Attenuation of sound during propagation outdoors - Calculation of the absorption of sound by the atmosphere Ingestion-build-65808 Detectors that detect thermal turbulence

Detectors that detect thermal turbulence within the optical beam as an adjunct to the detection of attenuation of an optical beam are covered although the thermal turbulence detection is not tested beyond ensuring that performance as an optical beam detector is not impaired

6 Conceptual model

The objective of this standard is to define limits and test methods for apparatus in relation to electromagnetic emissions which may cause interference in other apparatus

having average run lengths (ARLs) at the target level of at least 1 000 and 200 respectively

Although hydromorphology is dependent on hydrology and underlying geology
