what does the auricle do in a turfgrass?

Not sure it has a function ... auricles do not occur on all turfgresses. The auricle (means "little ear") is a small ear-shaped structure at the ligule of some grasses.

You can produce free-surface waves for example by dropping a stone at the center of a still mill pond.  The waves that propagate outwards have crests and troughs.  This is analogous to the waves produced in air by sound energy.  For example a trumpet player produces lip vibrations with his/her embouchure that allow the airflow (breath) to be interupted each vibration.  This emits a steady stream of sound waves where the air pressure is slightly above (condensation) and slightly below (rarefaction) atmospheric pressure.  The condensations and rarefactions correspond to the mill pond crests and troughs, respectively. Interestingly, the trumpet player's breath moves very slowly through the instrument (contributing to a slight dopler effect?) while the sound waves travel at the speed of sound (1,100 feet per second).  The sound travels from lip to bell in a tiny fraction of a second and there is even a second wave reflected back toward the lips.  The length of the round trip (and tone produced) depends on the length of horn selected by the trumpet keys (even easier to see in the slide trombone).  The concert A tone is 440 vibrations (trips) per second.  When lip vibrations exactly correspond with the sound wave cycles, resonance occurs and the note is sustained effortlessly.  Beginners try to force the vibrations (without regard for the length of path) and fail.  Singers produce the same type resonating air columns on both sides of the vocal chords, past the teeth and gums and can evey destroy a perfectly good wine glass with resonating energy.  Of course, sound can be emitted from a point source in space and the sound waves are produced as successive growing spheres of condensations and rarefactions similar to surface waves but truly three dimensional in space rather than affecting only a small layer of surface.  The spheres grow at 1,100 feet per second and the energy diminishes as it is spread over a larger spherical surface, although she spheres remain separated by the wavelengths of the pure tone.  A complex tone could better be pictured perhaps as a roller coaster stretched out straight in the directions the spheres are growing.  Your ears can intercept and interpret the roller coasters as song, voice or noise.  Hope that helps a little.

It lodges around your ear drum...like the first person said...it usually stays in your canal...until it ether evaporates or you pump it out

sebaceous glands in the ear produce the wax and it is to help move dirt and debris out

Well, its not really "music" that make plants grow. Its the sound waves in the air that trigger the plants growth hormone. In a sense, the plant thinks its being eaten, so it "wants" to grow. Talking to it, any kind of noise is helpful in their growth!

depends where in world u r. here most now that are built are sand based greens with drainage pipes underneath for extra drainage. then a mixture of sand and topsoil. u will find u get the best greens are seeded rather than turfed. than again depends on grass strains u use. dependin on climate and water levels u get.

The noseband is called a Shadow Roll and it's to prevent the horse from seeing shadows on the track when they are running because some horses will try and avoid the shadows and will try and swerve off course or try and jump them which could be dangerous.\n\nThe Blinkers are worn by horses who are on the spooky side or just easily distracted and will lose concentration by seeing other horses or movement on either side of the race track.

Apodization is a method for reducing side lobes in some arrays. It gradually decreases the vibration of the transducer surface with distance from it's center. It is usually accomplished by using more power to excite the innermost elements.   Subdicing is a technique used to overcome grating lobes: each major transducer element is devided into smaller parts, each one being a half wave length.

The chordae tendineae run from the atrioventricular valve leaflets to the papillary muscle.  The papillary muscles contain heart conduction fibers and contract during systole (heart ventricular contraction).  As the papillary contract the attached chordae tendineae prevent the valve leaflets from flapping back into the atrium.   They are present in the right and left ventricles.

It creates the acoustics of the guitar. That's why electric guitars don't have them.

I've heard that it works. Some people say that, where ever you position it on the ear, it works different ways.

Do you mean what else does the elephant's ear do (besides hearing)?\n\n1) the ear's large surface area, coupled with being extremely thin and having lots of blood vessels helps cool the blood and thus keep the elephant from overheating\n\n2) by flapping their ears, elephants can fan themselves to further help keep themselves cool\n\n3) sticking their ears straight out (like smaller animals perking up their ears) is a warning sign to who or whatever is confronting them to back off

I don't know about this particular stadium, but I believe most natural grass stadiums do NOT cover the grass for special events like concerts. Instead, they go about fixing any damage after the fact, usually by resodding.

Air is blown across reeds.  Kind of like a backward clarinet, which may account for the ... unique... sound.
