Analysis of acoustic design Fischer Audio Jubilate 64 Fabric cushions

The Fischer Audio Jubilate 64 headphones are made with closed-type acoustic design.

Due to the closed type the headphones have passive noise isolation and for the surrounding public the headphones play much quiet than for the listener. External sounds for the listener is on the same quiet level.

Headphones with noise isolation are good for home, when you need not to disturb others while listening to music. It's good in a noisy office, allowing you not to be distracted. In noisy transport playing music in such headphones is more safe for hearing, because due to noise isolation it is possible to listen to music at an average or quiet volume. In the studio, when recording vocals or instruments on a microphone, the closed headphones fit best; Sound from the "minus" of the headphones will not get into the microphone.

Headphones with noise isolation are dangerous to use on the street with active traffic.

Analysis of the sensitivity of Fischer Audio Jubilate 64 Fabric cushions headphones


The sensitivity of the Fischer Audio Jubilate 64 headphones is 116.14 dB/V SPL by the voltage and 105.16 dB/mW SPL by the power. The sensitivity by voltage reflects the relative "loudness" of the headphones among others - the higher is the value, the louder are the headphones. The sensitivity by power reflects the efficiency of the headphones. High sensitivity of the headphones means less energy need from the source (for portable devices - less power from the battery).

Depending on the sensitivity, headphones are best to use with sources of optimum power. If the source is too powerful, then there is a high probability of constantly hearing background noise. If source power is weak, there will be insufficient volume level.

In a quiet environment for the Fischer Audio Jubilate 64, an amplifier with a voltage level of at least -12.14 dBV at 80 Ohms is recommended for listening to music with a level of 90 dB SPL (without noise isolation). An amplifier with a level above 25.86 dBV is not desirable if the volume control is digital, not analog.

For noisy environments, an amplifier with a voltage level of at least -0.14 dBV at a load of 79.76 ohms is desirable.


If you want to listen to music at a different volume level, you just need to add or subtract a change in dB to 90 dB SPL (for example, for a desired level of 105 dB SPL, add 15 dB and the minimum voltage level for the amplifier is -12.14 dBV + 15 dB = 2.86 dBV).


Analysis of the impedance of Fischer Audio Jubilate 64 Fabric cushions headphones

The average resistance at the headphones Fischer Audio Jubilate 64 is 79.76 Ohm.

The resistance affects the amount of current that the amplifier should give to the headphones. If the current is not enough, the sound quality will deteriorate, beginning with harsh in the sound and ending with a crackling. In most cases, at low current values, the amplifiers operate in comparable quality to class A, and as the current level rises, the quality decreases toward AB, B, and the clipping zone.

Imagine that you have a water tank, which gradually fills with water. The voltage from the amplifier this is the pressure with which the pump draws water from the reservoir. If the inflow of water in the tank is lower than the volume that the pump pumps out, then at the pump outlet we collect water and "bubbles". Similarly will be with the sound from the headphones, which are lacked the current from the amplifier.

For a quiet environment, an amplifier with an output current level of at least 3.10 mA in a given class of quality is desirable (preferably orientated to comparable class A) and 12.34 mA for loud.

The average value of sensitivity by voltage for Over-ear headphones by measured 411 models is 111.9 dB/V SPL.

The Fischer Audio Jubilate 64 sensitivity is 116.1 dB/V SPL.

These headphones are 4.2 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 Fischer Audio Jubilate 64. A sufficient volume should be provided during playback and background noise from the source should not be noticeable.

In general, to listen to music with a level of 90 dB SPL in a quiet environment, the amplifier will require a voltage of -6.1 dBV.

It is desirable that the amplifier provides a margin of 12 dB in cases of rare noisy environments or for too quiet recordings. Thus, the amplifier should provide a maximum voltage level not lower than 5.9 dBV.

Excessive volume margin is undesirable, since for analog regulator, the adjustment range is about 40 dB and below that the channels imbalance begins. For a discrete regulator the pitch may be too large. For digital controllers are possible options for adjusting the sound level before a DAC or in a DAC. As a result of that will be decrease the signal-to-noise ratio and accordingly it is probable the appearance of audible noise.

The average sensitivity to power for Over-ear headphones is 99.1 dB/mW SPL (average by measured 411 headphone models). The Audeze LCD-2C sensitivity is 105.2 dB / mW SPL. Fischer Audio Jubilate 64 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.

Measurements of Fischer Audio Jubilate 64 Fabric cushions were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Fischer Audio Jubilate 64 Fabric cushions 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.
