The number of odour units in one cubic metre of gas under standard conditions (DIN EN 13725).

Measurement-based determination of odourant concentration, odourant flow and discharge conditions from localised and diffuse emission sources (e.g. as part of monitoring measurements) in accordance with DIN EN…

The total quantity of odorous substances contained in a liquid (e.g. process water or waste water) that can be expelled from the liquid (VDI 3885 Part 1).

The odour flow is the quantity of odour units passing through a defined area per unit of time. It is the product of the odour concentration, the discharge velocity and the discharge area, or the product of the odour…

A method for measuring odour immissions within a defined assessment area, using qualified human assessors over a sufficiently long period to be representative of the meteorological conditions at that location. The…

Determination of the odour-causing substances released when using raw materials (e.g. paints, solvents, etc.), expressed as a proportion of the mass of the raw material or in relation to other reference values. …

Odour propagation calculation.

Measurement-based assessment of odours in the field (e.g. in the vicinity of facilities, at points-of-interest, in planned development areas, etc.) using odour grid measurements or odour plume measurements. …

The strength of the odour perception triggered by an odour stimulus (VDI 3882 Part 1).

A collective term for the metrological determination of odours in the exhaust air of emission sources (odour emission measurement) or in ambient air (odour immission measurement).

Odour nuisance refers to perceptible odours in indoor spaces, which are detected through air sampling inside the room and close to the source in order to identify odour-causing substances by measurements. …

A method for determining the extent of the exhaust air plume from an odour emission source by determining the presence or absence of detectable odours at the edge of the plume for a specific emission scenario under…

The concentration of an odourant at the threshold of sensory perception or detectability, which does not provide any information about the sensory effect of an odourant at concentrations above this value (VDI 3940…

The quantity of an odourant or several odourants which, when vaporised into one cubic metre of neutral air under standard conditions, elicits the same physiological response from a group of test subjects (perception…

A substance that stimulates the human sense of smell in such a way that an odour is perceived (DIN EN 13725).

A branch of acoustics focusing on the generation and transmission of sound into the sea resulting from the construction and operation of offshore wind farms and offshore platforms.

OHS stands for Occupational Health and Safety. It refers to a management system, usually based on ISO 45001, which helps organisations to systematically reduce risks, prevent accidents at work and create a safe and…

A display technology in which each pixel generates its own light. OLEDs are characterised by deep blacks, high contrast and fast response times.

A device in which a sample of odorous gas is diluted with neutral air in a defined ratio and presented to test subjects (in accordance with DIN EN 13725). It is used to determine the odour thresholds of odorous gas…

Measurement of the test subject’s response to odour stimuli (in accordance with DIN EN 13725). The method standardised in accordance with DIN EN 13725 is used to determine the concentration of odorous substances in…

A measurement method standardised in DIN ISO 8297 for determining the sound power level relevant to immission from multi-source industrial installations (e.g. process fields in outdoor facilities). Directional…

Microphone without a directional pattern. Picks up sound from virtually all directions. Standard microphone for common sound level metres. Omnidirectional microphones are used, for example, for measuring sound…
