One philosophy that some persons question‚ including a few of our own aviation medical examiners‚ relates to our greater flexibility in granting special issuances to private pilots as opposed to air carrier and other commercial pilots. The arguments against such flexibility rotate around the thought that‚ in the event of a medical incapacitation‚ an air carrier or commercial pilot usually has another pilot on board who can take control of the aircraft and safely land. In contrast‚ the private pilot

When sound travels through air‚ the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound‚ and is measured in Hertz (Hz) - cycles per second. Loudness A loud noise usually has a larger pressure variation and a weak one has smaller pressure variation

the absorption coefficient α of MDF (Medium Density Fiberboard) and Fiber Cement through an improvised standing wave apparatus consist of an enclosed tube with a speaker on one end and the sample material on the other end. The maximum and minimum sound pressure developed inside the tube is measured by a moving microphone probe and the Standing Wave Ratio SWR and the absorption coefficient of the samples is calculated. The absorption behavior of each sample was also investigated in response to varying
