The manual manipulation should not, therefore, compromise the analysis of the relationships between pulmonary air pressure and acoustic output
During most trials (n=20), the acoustic output
was broadcast at a maximum sound pressure level of 62 to 72 dB (as measured using the RadioShack meter) at a distance of 3 cm from the speaker.
The speakers needed to overcome the challenges of surviving door slams and speed bumps, as well as meeting sound quality targets for more bass, efficiency and acoustic output
-- Anechoic Chamber -- Measures the amount and quality of acoustic output
to improve acoustic performance.
To help customers integrate rather complicated electromechanical hard drives into their consumer electronics products, CETEC can perform computer-based chassis evaluation; shock and vibration testing; shipping and inventory simulations with environmental chambers; acoustic output
measurements; error injection; packaging design; and care and handling training.
Bragging rights go to the company with the latest in a series of firsts--first to market, first with the current top in areal density, first with a new low in acoustic output
, and even first with proprietary drive diagnostics can earn a competitive advantage, all other things being equal.
The signal generator with PVDF requires more power than that with ceramic materials to generate the same acoustic output
