Vocalization enhancement

A number of recommendations can be made for the optimal use of spacers. Slow inhalation is preferable since the impaction of particles is proportional to velocity and particle size. A slow flow reduces the risk of impaction on valves and anatomic structures such as the pharynx or vocal cords. In addition, high flow rates enhance central airway deposition caused by inertial impaction and therefore reduce deposition in peripheral airways. 

Instrumental and Vocal Music. As specialists in the capture, enhancement, and reproduction of sound, audio engineers are crucial to successful recording sessions. They collaborate with producers and performers technically to generate the shared artistic vision. They determine the choice and placement of microphones and closely scrutinize the parameters of the incoming signals to collect sufficient data with which to work. They manage the scheduling of studio...
