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.

More detailed

Measurements of AKG K 72 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The AKG K 72 test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a source amplifier and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.

Comment to the AKG K 72 professional report
Hello.

I am trying to buy inexpensive over ear headphones. Information on the internet is overwhelming. Difficult to choose.

I have somehow come down to AKG K72 and Blaupunkt BH11. Features of BH11 are more but AKG is also quite appealing for many reasons. Now here is my dilemma.

(1) Information available of sensitivity of K72 is 112 dB spl/V. This information is on the AKG's own website.

(2) Whereas information available of sensitivity of BH11 is 105+3db. This information is on some other website.

So I don't know how to compare these 2 information. Both look scientifically different. Hence, I can't deduce which is better based on this information.

I am not an expert in the field of audio. I am just a consumer trying to buy the best in my budget. So I need your suggestions. Thank you.

105 + 3db possibly published to power. 105 dB/mW for 32 ohms is 120 dB/V SPL. https://reference-audio-analyzer.pro/dbv-dbmw.php?s=105&r=32&st2=checked

Здравствуйте, Роман. Благодарю за тесты наушников. Подскажите пожалуйста, для данных наушников (AKG K72) звуковая карта Asus Xonar U7 сильно слабовата будет?

Мне не запомнились K72 как наушники хорошего уровня, чтоб утверждать, что U7 не даст им как следует раскрыться. В идеале конечно для K72 желателен усилитель с большей отдачей тока, которого у U7 маловато.

Роман, благодарю. Имел в виду запас по гроскости с более-менее нормальным качеством звука.
К сожалению K72 в магазине не оказалось. Даже и не знаю как они звучат. Того же диапазона по стоимости ничего не приглянулось. Чтобы с пустыми руками не уезжать купил Sennheiser HD 206 чисто ради интереса. Честно говоря не ожидал, что они то и неплохие. Довольно ровные на слух. По гроскости с U7 как оказалось тоже нормально, с запасом (30-60% уровень в микшере).
