"The best standard as the first step when trying to learn what is publicly standardized in standards for headphones specifications and measurements"
If you are involved in the design and development of earphones and headphones as a designer, you will first learn the existing measurement methods that are often carried out in the organization you belong to. Since it is a measurement method that has been inherited in the organization, it is almost always the first step to learn this.
However, as your work experience becomes longer, you will need to talk with outside people. When you suddenly, you may know unfamiliar terms and measurement methods. It is natural because the performance of the earphones and headphones that are attracting attention differs depending on the company.
In such a case, it seems that you can often get the right knowledge by referring to a public standard.
Therefore, this time, the specifications and measurements from the classification of headphones and earphones are specified. It is "JEITA RC-8140C headphones and earphones".
JEITA is the English notation (JAPAN ELECTRONICS AND (JAPAN ELECTRONICS) Abbreviation for INFORMATION Technology Industries Association). We host CEATEC and Inter Bee, so many of you may know. In addition, it is an incorporated association that is active in a wide range of statistics such as shipments in the field of electrical and electronics and making policy proposals. We are also performing standardization of JEITA's proprietary standards, and the standards introduced this time are one of them.
You can refer to the following specifications by extracting the contents.
・ Classification and definition of headphones, earphones, headsets, ear sets, etc.
・ Specifying the left and right wards and polarity of wired cables and plugs
・ Specifications to be specified and how to measure them
These are very concisely described, so if you find the target items, you can quickly get the necessary information. In addition, since reference to the related standards is also described, even if you cannot find the desired content from this standard, you may get clues such as another standard document number.
