Частотная характеристика зависит от используемых стендов для измерений. Так как все стенды являются упрощенными или усредненными моделями людей, то результаты приблизительные. Максимально точный график можно получить лишь при индивидуальном измерении наушников на собственной голове с помощью
RAA Live Measurement System
.
Для коррекции АЧХ в первую очередь желательно использовать графики живых измерений от стендов
Human
, если такие есть в отчете. Особенно актуально это для
