Outer ear

Many people ponder over the thought on how they hear sounds, how their ears work, and how different sounds are perceived. Sound is in fact, just the vibration of the particles of an object, but the way the human ear distinguishes different sounds is truly fascinating. Many people have flawless hearing skills, but others have hearing disabilities that prevent them from being able to recognize different pitches of sound, or how loud or soft a sound is. This is defined as hearing loss, however,…

every aspect of life, and the function of the ears allows one to process these noises and send them to the brain. The human ear has three main parts that work together in order to perform the necessary job: the outer ear, the middle ear, and the inner ear. The outer ear, the section that is visible to the human eye, allows sounds to enter through the ear canal. The eardrum separates the outer ear from the middle ear. When sound reached the middle ear, the ossicles, which are the tiniest and most…

children is the condition otitis media with effusion, or also known as glue ear. Hearing loss typically occurs in part of the outer ear if it is congested. This then causes the sound waves incapable of reaching the middle or inner section of the ear. A conductive hearing loss can transpire in the outer or middle ear region containing poor conduction of sound along the channels leading primarily to the inner part of the ear. Due to this, sound is not focused well and is spread in a weaker and…

Our ears have an outer ear, middle ear, and inner ear. All of these sections play a role in allowing us to hear sound. The outer ear consists of the ear canal and the ear drum. The middle ear houses three tiny bones called the hammer, anvil, and the stirrup. On the other side of the bones there is a membrane called the oval window. The inner ear holds semicircular tubes and the cochlea. The cochlea is a bony tube shaped like…

with the ear and how the sound waves travel through from external to internal ear. The external layer of the ear consists of the auricle, external acoustic meatus, and the tympanic membrane. Sound enters through the auricle, which carries the sound waves to the external acoustic meatus (i.e. ear canal). The external acoustic meatus in turn carries the sound waves to the tympanic membrane (i.e. eardrum). After the sound waves have traveled through the external ear, they extent to the middle ear,…

standpoint this makes a person able to hear approaching threats and avert danger. Localization is the process in how we interpret the things we hear. How this works is through something called HRTFs and Binaural cues. The outer…

is a common health condition that affects more than 50 million Americans in the United States. Despite the fact that some of us have ears and have the ability to hear, many do not have a true understanding of the ear and how they work. To truly understand hearing and hearing loss, it helps to know the basics. Having a basic understanding about the function of the ears can help you better collaborate with your physician, and can lead to better hearing solutions. There are common, basic questions…

Did you know that ear buds can infect your hearing? Well, it isn’t the ear bud, it is the volume, most scientists say. You are supposed to have the volume turned low, or medium. Scientists say that the earbuds, and headphones aren’t the problem. It is the volume, it is tempting to turn it higher when you are on a train, or someplace where people are talking really loud. Some people lost their hearing, because of the volume of their music. Earphones can be good for blocking out background sound.…

Tinnitus is the ringing in the ear, which is an unwanted sound that one can hear. The sounds can be constant or comes and goes, soft or loud, and in one ear or both. There are three ways to distinguish the symptoms of the patient’s tinnitus sound: tonal tinnitus, pulsatile tinnitus, and musical tinnitus. Tonal is a near continuous sound that are affiliated with subjective tinnitus, which is just the normal ringing sound, pulsatile is pulsing sound that one hears from their heartbeat and for some…

basic types are conductive hearing, sensorineural hearing, and mixed hearing loss. Each of these losses has different causes. Conductive hearing loss happens when sound does is not conducted properly through the outer ear passages to the eardrum and through the ossicles in the middle ear. The resulting effect is a reduced sound level or inability to record faint sounds. Medical or surgical…
