С 2024 года измерения полноразмерных наушников в RAA проводятся не только на инструментальных стендах, но и вживую с помощью разработанной системы в RAA - Live Measurement System. Это позволяет увидеть реальное поведение наушников и их вариативность звучания относительно стандартных стендов. Результаты таких измерений в отчетах обозначаются как со стендов Human. В этом отчете - это:
Т.к. АЧХ зависит от посадки наушников и их прогрева/износа, то в RAA была разработан универсальный комплект Live Measurement System
для контроля своих наушников на собственной голове. Типовые комплекты доступны для приобретения.
