DASM – Providing Acoustic Testing Services for Electronic Equipment – Laptop Keyboards According to International Standard ISO 7779

DASM provides electronic equipment noise measurement services according to ISO 7779 standards. Ensuring accurate and reliable testing, supporting export and R&D.

In an increasingly sophisticated and fiercely competitive technological world, a seemingly minor detail such as... laptop fan noise or keyboard typing sound can become the deciding criterion for user choice.

So what should electronic manufacturing enterprises do to ensure their machinery not only "runs smoothly" but also "operates quietly"?

The answer lies in acoustic testing – according to ISO 7779 standards, and DASM Institute is the prestigious leading unit in providing acoustic services in Vietnam.

Why is acoustics important for technology products?

Imagine you are working in a quiet office, but your laptop hums like a jet engine every time you open a heavy file. Or you buy a high-end keyboard, but the clicking sound is so loud that colleagues turn around to look. Those experiences, however small, directly affect user perception and, in the long run, impact brand value.

Nowadays, major manufacturers all understand that:

A good product is not only stable in operation – but also quiet, sophisticated, and non-disturbing to the user.

And to prove that, they need a methodical testing process – meeting international standards.

ISO 7779 – The global standard for IT equipment noise testing

ISO 7779 is an international standard specifically used to measure noise emitted from information technology and office equipment such as:

• Laptops, desktop computers
• Printers, photocopiers
• Cooling fans, cooling systems
• Input devices such as keyboards, mice
• Electronic products with sound-producing components

This standard strictly regulates everything from test room conditions, measuring equipment, microphone placement positions to data processing methods – ensuring objectivity and global comparability.
