Staff mobility is a reality in the modern world. A great number of employees take part in different meetings and conference while travelling on business or even on vacations. Employees join teleconferencing using their mobile devices, although background noises annoy both themselves and other teleconference participants. Conferences take longer than planned and become less effective.
Petralex formula deals with counting the amplification coefficients for correction of amplitude-frequency characteristic of a sound reproduction device. The main idea is that normal (without any pathological changes) person’s hearing has a certain audibility limit in silence, and by using this limit amplitude-frequency characteristic of a sound reproduction device can be estimated.
