Headphones EN50332–2

Headphones are the electronics we often use, but listening to concerts at a loud volume for long hours hurts your ears.

The sound pressure, output voltage and audio stability test of the portable playback device are specified by the EN50332.

The test range includes all portable audio devices with headphones or headset sockets and individual headphone products.

EN50332 test classification:

EN50332 is divided into two parts, EN5032-1 and EN50332-2. And EN50332-2 is divided into EN5032-2-1 (player output voltage) EN5032-2-2 (headset Broadband characteristic voltage test). The EN5032-1 includes the maximum sound pressure level measurement, for the performance of the player and the headset, the EN5032-2 includes two tests of the maximum output voltage and the broadband characteristic output voltage of the headset.

EN50332 test requirements:

1. The product shall be tested in the silent room (silent room) to avoid interference from environmental noise.

The headphones are mounted on standard artificial ears, and the microphone is mounted to collect the sound of the headphones.

Audioanalyser Analyze and record the maximum sound pressure value (LAeq) for each audio. The standard sound source used in the test is the IEC60268-1.

2. The signal intensity of audio products playing digital signal (CD, DVD, MP3) is 10dB, and analogue signal cassette is-6dB.

The FM radio requires an antenna to transmit a passenger carrying signal (-6dB) in order to receive it.

Adjust the sound volume to the maximum volume, a total of 5 times measured, take 5 times the average.

C-tick authentication concept A/c-tick is A certification mark for Communications equipment issued by the Australian Communications Authority (ACA).Manufacturers and importers must follow the next step in using A-Tick: : 1. Product implementation ACAQ technical standard test 2. Register the use of A/C-Tick to ACA 3. Fill in the Declaration of Conformity Form and keep the product with the record C - tick certification In communication products or equipment with A/C - the identity of the Tick marks (label) 5, sales to consumers A - Tick only applies to communication products, electronic products, mostly apply C - Tick, but electronic products if the application is A - Tick, do not need to apply for the C - other Tick.Since November 2001, EMI in Australia/New Zealand has applied for a merger;If the product is to be sold in the two countries, the following documents must be in place before marketing, in case the authorities of the Australian Communications Authority or the Ministry of Ec

IC is short for Industry Canada, a government agency that is responsible for the certification of electronic products entering the Canadian market.Its products are generally divided into: broadcast television equipment, information technology equipment, radio equipment, telecommunications equipment, engineering medical equipment, etc. Like the FCC in the u.s., IC currently only restricts electromagnetic interference. IC authentication method: There are two ways of Certification and Certification. IC ID: CN (Company Number, up to 6 digits) +UPN (Unique Product Number, up to 8 bits). ID application: 1. The address information of the representative of Canada must be provided. 2. The label shall include the following information (manufacturer name or trademark, model name, IC ID number). Related standards of IC certification: IC certification standards are basically in line with the FCC, and IC currently only restricts electromagnetic interference. Y-001 analog equipment: Industrial, Sc
