Analysis of acoustic design Sennheiser HD 598

The Sennheiser HD 598 headphones are made with an acoustic design of an open type.

Due to the open type, the headphones do not have noise isolation - the people around can hear well the music from the headphones, while you can hear ambient sounds too.

Headphones without noise isolation are well suited for home and studio in a quiet environment, as well as on the street with active traffic, allowing you to notice the danger in time.

Headphones without noise isolation are unsuitable for use in noisy public transport, as due to external noise it is necessary to increase the volume level of reproduced music, which is harmful for hearing during long listening. Loud sound is unpleasant to passengers nearby. In a studio, while recording vocals or instruments by a microphone, the open headphones are likewise not suitable, because sound from the "minus" from the headphones will gets into the microphone.

Analysis of the sensitivity of Sennheiser HD 598 headphones


The sensitivity of the Sennheiser HD 598 headphones is 111.49 dB/V SPL by the voltage and 100.71 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 Sennheiser HD 598, an amplifier with a voltage level of at least -1.49 dBV at 84 Ohms is recommended for listening to music with a level of 90 dB SPL (without noise isolation). An amplifier with a level above 36.51 dBV is not desirable if the volume control is digital, not analog.

For noisy environments, an amplifier with a voltage level of at least 10.51 dBV at a load of 83.55 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 -1.49 dBV + 15 dB = 13.51 dBV).


Analysis of the impedance of Sennheiser HD 598 headphones

The average resistance at the headphones Sennheiser HD 598 is 83.55 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 10.09 mA in a given class of quality is desirable (preferably orientated to comparable class A) and 40.15 mA for loud.

Measurements of Sennheiser HD 598 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Sennheiser HD 598 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.
