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: Human: romanrex

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.

Brief information

The graphs show the frequency response of the headphones without compensation to the target curves. Additionally, the basic target curves are shown. The frequency response depends on the measurement stands used. Since all artificial stands are simplified or averaged models of people, the results are always approximate.

The HDM-X stand uses the concept of a binaural microphone with microphone caps positioned at the entrance to the ear canal. The unevenness in the high frequency range above 2~3 kHz is formed from the shape of the auricle, the fit of the headphones on the stand and the relative internal volume between the ear and the driver. There is no resonance from the ear canal in this type of stand.

Human - is a live measurement with miniature microphones inserted into the ear canal as in-ear headphones with the deepest fit. Such measurements most accurately show the low-frequency and mid-frequency range, since they take into account the real pressure of the ear pads and damping of the real head. The high-frequency range is less accurate with this measurement, because it depends on the fit of the microphone in the ear. Since 2024, all headphones are measured on the head of the founder of the RAA project and in some cases on the head of the owners of the headphones as part of an individual calibration.

For overhead and full-size headphones, the basic target curve RAA v1 with low-frequency correction from Harman Target Curve Over-Ear 2018 is given.

The combined frequency response of the Sennheiser HD 560s with various amplifier sources is shown in an additional summary report.

The export of the frequency response graph is available on the comparison pages, which can be accessed using any graph from the report below. A separate summary report shows the recommended Sennheiser HD 560s equalization settings and a comparison with various target curves.

Brief information

The impulse response is a reaction to a single pulse of the shortest possible duration

The step response is a playback on a step (front square) signal. It is built on the derivative impulse response. According to the transition characteristic, the correct polarity of the inclusion of radiators in the speaker is usually determined.Most of the studied parameters are calculated from the impulse response: frequency response, phase-frequency response, group delay, Watterfalls, step response and square wave.

Since the waveform of the impulse response primarily depends on the frequency response and attenuated resonances and reverberation of the headphones themselves and the camera of the stand, the visual visibility of the parameters directly on the impulse response is extremely low. To obtain most of the characteristics, the fast Fourier transform and other mathematical algorithms with analysis of the total impulse length are used. The total pulse length is about 5 seconds, while visually the pulse is displayed with a duration of 2-4 milliseconds. Vertically, the visual detail does not exceed 40-45 dB. Thus, for a visual view, an alternative view is used from the sum of the half-wave modules of the impulse response shown on a logarithmic scale.

The visual definition of frequency response and resonances by impulse response was relevant only in "pre-computer" times. Today, according to the impulse response, only the same or different polarity of the emitters and the possible high-frequency resonance are looked at, if there is no graph of attenuated resonances. There is an opinion that the impulse response "immediately shows everything", and its absence is a concealment of the truth. Here the impulse response is given to dispel this misconception. Additionally, you can see the dependence of the shape of the impulse response on the stand.

When testing the speakers, the reverberation of the room is determined by the impulse response. The headphones work on a small volume and there is no reverberation from late reflections and this characteristic does not show useful data. The impulse response on a logarithmic scale is given for general educational purposes - to show that the usual type of impulse response is not a short burst of 2-4 ms, but a long-term attenuation for several seconds.

RAA measurements are made in 192 kHz / 24 bit mode.

The impulse response is displayed as is, without compensation of the frequency response for the microphone or smoothing. It is RAW data. The reduction in the frequency response of the microphone starts at 20 kHz. The lower limit is from 2~4 Hz.

Brief information

Thecumulative spectrum of the signal attenuation shows resonances and reverberations after the headphones cease to reproduce the signal.

The change in the cumulative spectrum of the signal attenuation is a cumulative spectrum of the signal attenuation, where the original frequency response is represented by a straight line.

The cumulative spectrum of signal attenuation is constructed by impulse response . The graph does not use three-wave smoothing. Time zones with an interval of 1 ms are painted in a certain color. For convenience of perception, the graph does not have vertical displacement, limited only to horizontal displacement. From the position of 3D - this is a view with a small turn in the horizontal plane. You can accurately assess the level on a vertical scale. To obtain good resolution in the time domain, a small window of 2048 samples is used, which directly affects the low resolution of the low frequency region and the graph in the region below 200-300 Hz does not show useful information.

More detailed

Measurements of Sennheiser HD 560s were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Sennheiser HD 560s 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.
