![]() Read a research paper about these objects here. The nylon used to manufacture this tuning fork is a food grade nylon. The note produced is considerably lower than that produced by the copper tuning fork. Similar to the spruce tuning fork, it produces no audible sound when struck but can produce a very low note that doesn't ring for long using the pinch technique. The fork is relatively warm to the touch. This nylon tuning fork is off-white in colour and has a dull matte finish. These material properties will also affect how high or low the note that is produced is (acoustic pitch) as well as how long the tuning fork rings for (acoustic brightness). When these tuning forks are struck, the density and elastic modulus of the material determine how much energy is absorbed and how much is converted into vibrations and audible noise. Playing these tuning forks allows us to directly compare how the density and elastic modulus of each material affects the sound the fork produces. Each of the set of tuning forks is the exact same shape, but is made from a different material (an array of metals, woods, plastics and glass). tuning fork placed on each medial femoral condyle and patella in turn. Three principle factors influence the production of sound by a tuning fork: the shape of the fork, and the density and elastic modulus (a measure of stiffness) of the material from which the fork is made. Another method to diagnose a fracture of the femur neck is the Barford Test. fracture, examined them using the tuning fork test fol-lowedbyabonescan. After history and clinical examination tuning fork test (TFT) was performed on each case. scaphoid fractures and, after their vibratory tests, were eliminatedfromthestudy.Theremainingfiftypatients,39. X-rays of all the subjects were unremarkable. Methods: The current study examined 55 subjects whose age ranged 18-28 years. ![]() ![]() Together these tuning forks investigate the acoustic properties of materials and demonstrate the physics of sound and vibration. The purpose of the study was to evaluate the efficacy of tuning fork in stress fractures by comparing it with three phase bone scan. ![]() This nylon tuning fork is one of a set of 16 made in 2009 by our Director Zoe Laughlin as part of her PhD research. These applications all rely on the fact that when a tuning fork is struck, that energy is converted into vibrational energy, and its tines oscillate at a particular frequency to produce a specific pitch of note. They can also apparently be used by medics to detect a bone fracture in a pinch if no x-ray is available. They are used by audiologists to test for certain kinds of hearing loss, by the police to calibrate the radar guns used to identify speeding vehicles, and by alternative healers as an (unproven) way of improving mental clarity and physical energy. Tuning forks are so named because they are used to help tune musical instruments, but they also have a variety of other uses. ![]()
