This is an audio version of the Wikipedia Article:
ISO 14644

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
ISO 14644 Standards were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. The need for a single standard for cleanroom classification and testing was long felt. After ANSI and IEST petitioned to ISO for new standards, the first document of ISO 14644 was published in 1999, ISO 14644-1.In 2000, ISO 14644-2 was published, which began the process of FED-STD-209E being canceled. On November 29, 2001, the document was canceled and superseded by ISO 14644-1 and ISO 14644-2.
ISO 14644 is now composed of
ISO 14644-1: Classification of air cleanliness
ISO/DIS 14644-1.2(2014): Classification of air cleanliness by particle concentration
ISO 14644-2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1
ISO/DIS 14644-2.2(2014): Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration
ISO 14644-3: Test Methods
ISO 14644-4: Design, Construction, and Start-up
ISO 14644-5: Operations
ISO 14644-6: Vocabulary
ISO 14644-7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments
ISO 14644-8: Classification of airborne molecular contamination
ISO 14644-9: Classification of surface particle cleanliness
ISO 14644-10: Classification of Surface Cleanliness by Chemical Concentration
ISO 14644-12: Classification of Air Cleanliness by Nanoscale Particle Concentration
