Test codes for sound absorption measurements
Nils-Åke Andersson CEN/TC 126, Building acoustics, has created a working group, WG 11, to develop Test Codes for suspended, acoustic ceilings. WG 11 started its work about a year ago with Nils-Åke Andersson from Saint-Gobain Ecophon as convener and has now about 15 participants from around Europe. The reason doing this work is the problems […]

Zebrafish might save human hearing!
The most common cause of hearing loss is damage to the hair cells in the inner ear. Once hair cells die, humans (like other mammals) aren’t able to grow new ones. Zebrafish, unlike humans, are able to regenerate their damaged hair cells. US researchers hope knowledge about this can help humans in the future. A […]
