Aerometer Explained

An aerometer is an instrument designed to measure the density (among other parameters) of the air and some gases.[1]

The word aerometer (or Ärometer, from Ancient Greek ἀήρ -aer "air" and μέτρον -métron "measure, scale") refers to various types of devices for measuring or handling of gases. The instruments designated with this name can be used to find: the density, the flow, the amount or some other parameter of the air or a determined gas.

Several different designs of aerometer have been developed for the study of speech.[2] These make use of a mask fitting closely to the speaker's face, usually with a partition separating airflow from the nose from airflow from the mouth.[3] Various designs of transducer convert the flow of air into electrical signals.

Another instrument called areometer (from Ancient Greek ἀραιός -araiós "lightness" and μέτρον -métron "measure, scale"), also known as hydrometer, used for measuring liquids density, is often confused with the term aerometer here defined.
