Interactive Ear tool showing how the ear works by Amplifon The ear is the organ which controls hearing and balance, allowing us to understand our surroundings and position ourselves correctly. It is split into three parts: outer, middle and inner. This guide will take you through each part of the ear in turn, answering those essential questions – what are the parts, what do they do, and how? Pinna Helix Antihelix Concha Antitragus Lobe Cartilage Temporal Muscle (Temporalis) Temporal Bone Semicircular Canals Ganglia of the Vestibular Nerve Facial Nerve Ear Canal (External acoustic meatus) Mastoid Process Internal Jugular Vein Styloid Process Internal Cartoid Artery Eardrum (Tympanic Membrane) Auditory Tube (Eustachian Tube) Outer Ear – Welcome to the Interactive Ear! This is the part of the ear that people can see, and funnels sound into your ear canal. The rim of the pinna. A curved panel of cartridge. Bowl-shaped part of pinna. The small, hard bump above your ear lobe. The earlobe contains a large blood supply, helping to keep the ears warm.

Music Theory for Musicians and Normal People by Toby W. Rush This page includes links to each of the individual Music Theory pages I've created in PDF form. This is a work in progress; I am writing new ones regularly and fixing errors and omissions on existing ones as I find them. If you find them useful for your theory studies, you are welcome to use them, and if you find errors or have suggestions, I invite you to contact me. These pages are available for free under a Creative Commons BY-NC-ND license. This collection is a work in progress, but if you would prefer, you can download all the current pages as a single PDF. If this makes you excited enough that you'd like to purchase a theory-related shirt, hat, bag, button or sticker, visit my T-shirts And Other Stuff page.

Implants | Hearing Loss Treatments | Cochlear™ Aust/NZ A cochlear implant is an electronic medical device that does the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain. What is a cochlear implant? A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain. Who can they help? Cochlear implants can help people who: have moderate to profound hearing loss in both ears have profound hearing loss in one ear with normal hearing in the other ear receive little or no benefit from hearing aids score 65% or less on sentence recognition tests done by hearing professional in the ear to be implanted Many people have cochlear implants in both ears (bilateral). How do they work? Many people suffer hearing loss because their hair cells in the inner ear or (or cochlea) are damaged. Show All Close All

LilyPond – Music notation for everyone: LilyPond... music notation for everyone Hearing Aids | NIDCD What is a hearing aid? A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one. A hearing aid has three basic parts: a microphone, amplifier, and speaker. How can hearing aids help? Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. A hearing aid magnifies sound vibrations entering the ear. How can I find out if I need a hearing aid? If you think you might have hearing loss and could benefit from a hearing aid, visit your physician, who may refer you to an otolaryngologist or audiologist. Styles of hearing aids

6 Open Source Software Projects of (Musical) Notation As it's been pointed out before, there seems to be a sizable overlap between open source hardware and software enthusiasts and amateur musicians. And while some of you are making music through the tried-and-true "let's see what that button does" method, there are a few of you who might be interested in composing music the old-fashioned way -- digitally producing paper-based music sheets. Whether you're writing music for the guitar, learning how to improvise jazz solos, or writing entire music scores, chances are that one of the pieces of open source software listed below can make the process a little easier. Generalized Music Notation Software If you're interested in arranging, composing, or transcribing music, these might be good resources to keep handy. Denemo: Denemo is a music notation program that lets you input music using the number pad on your keyboard and then edit it using your mouse. Guitar-Specific Notation Software Music Theory Software

How do animals see in the dark? - Anna Stöckl While most of us take it for granted that we can perceive the world around us through our eyes; in all its colors, richness of detail, and movement; this is not self-evident for all animals on this planet. For those active at night, the sparse light makes vision, which depends on the abundance of light, problematic. What is it about the night that makes animals chose it over the day, despite the challenges it holds for them? But it is not just animals active at night that need to tackle the challenge of sparse photons for their sense of vision. What is so special about the sense of vision that so many animals have evolved adaptations to be able to use vision as one of their primary senses when active in dim light? Learn more about the human eye with this TED-Ed Lesson: A journey through the human eye. While we humans are not primarily night active creatures, we also have some specializations for seeing in dim light.
