| acoustic filter (A device employed to reject sound in a particular range of frequencies while passing sound in another range of frequencies) | akustisk filter | |
| acoustic insulation (The process of preventing the transmission of sound by surrounding with a nonconducting material) | lydisolasjon | |
| acoustic level (Physical quantity of sound measured, usually expressed in decibels) | akustisk nivå | |
| acoustic property (The characteristics found within a structure that determine the quality of sound in its relevance to hearing) | akustisk egenskap | |
| acoustical quality (The characteristics of a confined space that determines its ability to enable music and speech to be heard clearly within it) | akustisk kvalitet | |
| acoustics (The science of the production, transmission and effects of sound) | akustikk | |
| act (1. Something done voluntarily by a person, and of such a nature that certain legal consequences attach to it. 2. Documents, decrees, edicts, laws, judgments, etc.) | lov | |
| actinide (A group of 15 radioactive elements some of which occur naturally while others are produced in nuclear reactions. They include plutonium, americium and neptunium. The health hazard presented by the actinides, if they are released into the environment, comes from the potency of their radioactive characteristics. They are alpha-emitters, and therefore can cause intense localized damage in tissues if absorbed into the body) | actinoid | |
| actinium (A radioactive element of the actinide series, occurring as a decay product of uranium. It is used as an alpha particle source and in neutron production) | actinium | |
| action group (A collection of persons united to address specific sociopolitical or socioeconomic concerns) | aksjonsgruppe | |
| activated carbon (A powdered, granular or pelleted form of amorphous carbon characterized by a very large surface area per unit volume because of an enormous number of fine pores) | aktivkull | |
| activated sludge (Sludge that has been aerated and subjected to bacterial action; used to speed breakdown of organism matter in raw sewage during secondary waste treatment) | aktivslam | |
| active participation (The involvement, either by an individual or a group of individuals, in their own governance or other activities, with the purpose of exerting influence) | aktiv deltakelse | |
| active population (The number of people available and eligible for employment within a given enterprise, region or nation) | yrkesaktiv befolkning | |
| adaptable species | tilpasningsdyktig art | |
| adaptation period | adapsjonsfrist | |
| addition polymer (A polymer formed by the chain addition of unsaturated monomer molecules, such as olefins, with one another without the formation of a by-product, as water; examples are polyethylene, polypropylene and polystyrene) | tilsatspolymer | |
| additional packaging (Additional packaging around the normal sales packaging. For example as protection against theft or for the purpose of advertising; the customer may leave the additional packaging in the shop for waste collection) | tilleggsemballasje | |
| additive (Substances mixed in small quantities with another product to modify its chemical or physical state. Additives are used to make food look visually more attractive, in the case of colouring agents, as well as to preserve and extend the life of the product) | tilsetningsstoff | |
| adequate food supply (A quantity of nutriments that meets fundamental nutritional requirements and is provided to a person, group or community on a continuing basis) | adekvat matforsyning |
