Question 10 2 / 2 pts The measurement of sound intensity is logarithmic and a rule of thumb for perceived loudness is that it doubles for every 10 dB increase in sound intensity. True False Incorrect Question 11 0 / 2 pts Sensory illusions involving primarily the semicircular canals are often referred to as _________ illusions. somatogravic somatogyral somatological

G-excess Question 12 2 / 2 pts The physical characteristic of sound which gives the physiological and psychological sensation of pitch is called _________. intensity frequency (Hz) wavelength (dB) modulation Question 13 2 / 2 pts Aircraft engine noise is usually _________ during takeoff and ________ during descent.

After recovering from a prolonged spin (or spiral dive), you may experience a strong sensation of turning in the _________ direction of the original angular motion. This may cause you to inadvertently enter a spin (or spiral dive) in the _________ direction of the original spin (or spiral dive). opposite; opposite same; same opposite; same same; opposite Question 16 2 / 2 pts When both speech and noise levels are about the same (SNR = 1), most speech communication is understood because of the context in which the individual words are used. True

False Question 17 2 / 2 pts The ratio of applied acceleration (a) — or aircraft-maneuver-induced acceleration — over the acceleration of gravity (g), is used to describe the total acceleration (or “G - force”) on an aircraft and its pilot (G = a/g). True False Question 18 2 / 2 pts _________ acceleration occurs when there is a change in the direction of an object, such as occurs during a turn, or during a push into, or a pullout from, a dive. Radial Angular

Linear Circular Incorrect Question 19 0 / 2 pts Sound wave energy is substantially reduced when passing from a gas (air in outer ear) to a liquid (fluid in inner ear); but the unique mechanical arrangement of the middle ear makes up for this limitation by amplifying the sound energy by as much as 25 dB. True False Question 20 2 / 2 pts Airframe noise is partly a function of indicated airspeed (dynamic air pressure) expressed as 1/2ρV2, where ρ (rho) is the density of the air and V is the true airspeed. Therefore, the slower the airspeed and higher the altitude (lower air density), the greater the aerodynamic noise created around the aircraft’s fuselage. True

False Question 21 2 / 2 pts ________ acceleration (+GZ) is headward acceleration (or eyeballs down) that you could experience in a steep turn, an inside loop or a pull-up from a dive. Positive transverse Positive vertical Negative lateral Negative vertical Incorrect Question 22 0 / 2 pts During the first decade of this century alone, almost 1,000 people lost their lives in airline accidents involving SD.

True False Incorrect Question 23 0 / 2 pts Grayout and blackout are caused by ________ hypoxia. Stagnant hypoxic histotoxic hypemic Incorrect Question 24 0 / 2 pts

________ orientation (sometimes called postural or proprioceptive or kinesthetic orientation) involves sensors in our muscles, tendons, skin, and joints that respond only to acceleration (including gravity) and is often referred to as the “seat of the pants” sensations. Somatosensory Vestibular Otolith Coriolis Question 25 2 / 2 pts The organ in which the back-and-forth movement of tiny hair cells hair cells is converted into neural impulses that are sent to the auditory cortex of the brain and interpreted as sound, is the _________. hammer
