shows the frequency volume balance (tonal balance) similar to the equalizer setting enabled for headphones or speakers with "even frequency response". The frequency response can be used to estimate the volume balance between frequency ranges and a type of frequency response. The average level is taken for 0 dB. Where the values are negative, the frequency ranges are quieter than the average level, and where positive, on the contrary, louder.
In ideal conditions, headphones should have the same frequency response as speakers with flat frequency response. But due to the complex shape of the human auricle, we have increased sensitivity in the high frequency region. he frequency response from the sound source varies depending on the rotation of the head to this source. Thus, the frequency response of the headphones should correspond to the conditional target frequency response, which should be subjectively close to the smooth perception of sound in the headphones.
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 perception of frequency response additionally depends on various external conditions, whether we listen to headphones quietly or loudly, on the street or at home, whether the headphones have noise insulation or not, etc.
To evaluate the sound of headphones for yourself, you need to add various corrections to the base target curve and get the final target curve - a multitarget.
The graph additionally shows the target curves for listening to headphones at different volumes. The middle line correlates with the natural volume, which in turn can be different for different genres of music: from 70 dB SPL for acoustic recordings to 90 dB and above for heavy rock music. Here, the deviation of the volume at which the headphones are listened to from the volume at which the music would sound live is estimated.
The upper line shows the desired frequency response of the headphones for listening at a low volume, 20 dB below the natural level. This can be listening to music at night or listening in the background while working or relaxing. As the volume decreases, we subjectively feel the lowest and highest frequencies more quietly than the middle frequencies.
The bottom line, on the contrary, shows the desired frequency response for louder listening, above the natural volume by 20 dB.
More settings for the target curve are presented in the Multitargeting / Equalizer Settings report, and you can configure the target curve in detail and upload settings for the equalizer on the frequency response comparison page (you can go to it using any graph in this report).
Also, the frequency response of the headphones changes when connected to different sources due to the mutual unevenness of the headphone impedamce and the amplifier impedance
. The professional report provides the most common source options and changes in the final frequency response. In the RAA comparison tools, it is possible to connect various measured headphones and sources in the constructor, and compare such bundles with each other.
The frequency response depends on the measurement stands used. Since all the stands are simplified or averaged models of people, the results are approximate. The most accurate graph can be obtained only by individually measuring the headphones on your own head
.
The average value of sensitivity by voltage for Over-ear headphones by measured 1831 models is 110.2 dB/V SPL.
The Sennheiser HD 280 Pro (mk2) sensitivity is 116.6 dB/V SPL.
These headphones are 6.3 dB louder than most Over-ear headphones.This difference is insignificant and not exceeding a threefold deviation from the mean. So, most devices designed to work with full-sized headphones should fit quite well with the HD 280 Pro (mk2). A sufficient volume should be provided during playback and background noise from the source should not be noticeable. Knowing the sensitivity value of the headphones, you can predict the relative difference in volume between the headphones. But, more practically, this is the volume level of a bunch of headphones and amplifiers. In the RAA tool, the sound pressure in a bundle can be selected from headphones and amplifiers, and roughly representing the capabilities of a familiar bundle, you can understand how much quieter or louder the other bundles will be.
In a professional way, this is done in the service interaction of the joint frequency response of headphones and amplifiers.
The Sennheiser HD 280 Pro (mk2) sensitivity is 105.0 dB / mW SPL. HD 280 Pro (mk2) have greater sensitivity than other headphones of this type. This means that their power consumption is lower and being connected to mobile devices, the operation time of this bundle will be longer than of many others.
You can recalculate the sensitivity from voltage to power and vice versa in the appropriate calculator
.
A difference of 6 dB means a two-fold difference in volume. For example, if you turn on two speakers instead of one, the sound pressure level will be 6 dB higher. If you turn on four speakers instead of one, then by 12 dB. If you turn on three speakers instead of six, the level will decrease by 6 dB. You can read more about decibels separately, and listen to the difference in decibels yourself.

More detailed
Measurements of Sennheiser HD 280 Pro (mk2) were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The Sennheiser HD 280 Pro (mk2) 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.
