Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too. Your experience can provide helpful information to someone looking for a great hearing care provider, reward a clinic for taking good care of their patients and create a sense of community where you live. Did you make a New Year’s resolution to finally have your hearing evaluated by a professional?
It could be a noisy workplace, the constant drumbeat produced by MP3 players and other digital music players or the constant drone of traffic right outside the window.
Noise induced hearing loss, the only type of hearing loss is fully preventable, is on the rise and is seen in younger generations. There are many ways to prevent noise induced hearing loss such as turning down the volume and wearing hearing protection while around loud noise such as power tools and concerts.
People with diabetes are more susceptible to hearing loss, as well as people with cardiovascular conditions or heart disease. Always read the warning labels on any meds you buy over the counter and ask your doctor about the side effects of any prescription medications you take.
However, we do know that damage to the hearing centers of the brain and damage to the delicate hearing mechanism that converts sound waves to electrical impulses lead to hearing loss – the permanent kind. See an audiologist or hearing aid practitioner – an expert in hearing, hearing loss and hearing solutions. Then, working with you, the patient, these hearing professionals will offer a number of solutions from which to pick. Your hearing professional will discuss with you the hearing test results and identify just how much hearing you’ve lost and in what sound frequencies that hearing loss has occurred. It is important to work one-on-one with a hearing professional to select the best hearing aids for you, your hearing loss and budget. However, some hearing aid users don’t like the stuffy feeling CICs create so they cross that type off the list and not to mention CIC hearing aids are typically ideal for more mild hearing losses. For those who want a more natural fit and feel, they opt for open-fit BTEs and RIC hearing aids.
Open-fit BTEs and RIC hearing aids are also cosmetically appealing for those concerned about the cosmetics of wearing hearing aids.
It’s the beginning of a new decade, the beginning of a new year and the beginning of new ears for you. There may be a natural tendency for dispensing professionals to recoil at the idea of a tuning fork test; it seems dusty and archaic in the face of all of our excellent electronic screening options. Prior to the introduction of electronic audiological testing equipment, clinicians relied heavily on tuning fork tests (TFT) along with some other rudimentary tests, such as the “Whisper Voice.” Even with all of the electronic and computerized test equipment available today, TFTs play a critical role as an adjunct for clinicians to determine the type of hearing loss in patients. Although some of the TFTs have lost their value, two tests—the Weber and Rinne—have stood the test of time and are still important for clinicians in diagnosing hearing loss. Tonndorf and others10-12 have pointed out the important contribution that TFTs make for clinicians in developing their otologic diagnosis.
Tonndorf and colleagues11,12 offered the most detailed and complete explanations of how bone conduction (BC) works. 1) Middle ear inertia, 2) Middle ear compliance, 3) Inner ear compression, and 4) Round window release. 5) Inner ear fluid inertia, 6) Oval window release, and 7) Release through the “third window” (cochlear aqueduct). Tonndorf12 comments, “All three anatomical parts of the ear, the outer ear canal, the middle ear, and the inner ear, contribute independently to bone conduction [transmission].” He went on in a later paper11 to further clarify his theory of bone conduction. Tonndorf stated that 500 Hz and 1000 Hz are the frequencies that are most affected by middle ear inertia.10 With the Rinne test, at frequencies above 1000 Hz, the air-bone gap has to be larger in order to observe the fork being louder behind the ear compared to at the opening of the meatus.
Clinically speaking, we know quite a lot about tuning fork tests; however, the mechanisms explaining the interaction of the components can be confusing. The Weber and Rinne should be administered at a BC level of 40 to 50 dB HTL (hearing threshold level) using a bone oscillator at 500 Hz or 1000 Hz.11 When a tuning fork or bone oscillator is overdriven and made so loud it deviates from its fundamental frequency, it will produce distortion. It should be noted that it is common to use the term 512 Hz and 1024 Hz when referring to a tuning fork test.
In the Weber test, the tuning fork tines are set into vibration and the stem of the fork is pressed against the middle of the forehead.
If a conductive, mixed, or sensorineural hearing loss is present in only one ear and the other ear is normal or has better sensorineural hearing, the patient will report hearing the fork in that ear with the conductive loss or the ear with greatest sensorineural loss.
In administering tuning fork tests, we have found that patients have no difficulty reporting their observations to the clinician. This paper was written with the intention of communicating to hearing care clinicians an explanation of two tuning fork tests, the Weber and Rinne.
The Weber and Rinne can be administered and communicated in only a few minutes and can be valuable in assisting hearing care professionals in interpreting and verifying their own test results. The Heart of the Matter: What Does America Really Know about Coronary Artery Disease Treatments? The SWANEE WHISTLE or FLUTE PISTON or FLUTE PLUNGER is a idiofono, great fun for the possibilities of sound, besides being used in the musical education of children.
This flute is constructed of metal and can produce a wide range of sounds, is used for special effects, children, clowns, entertainment, etc..
The possibility of expanding or contracting the rod to change the pitch makes it an instrument similar to a trombone rod, but with a flute sound, which soon after use can easily play any song, which allows learners to go ear and the ability to play any song. In fact, by making a few lifestyle changes and getting fitted with a pair of today’s high-tech hearing aids, you can live the life you used to live and hear the richness of life the way it was meant to be heard. If you are exposed to workplace noise, talk with your employer about providing you hearing protection. Poor circulation of blood and oxygen can affect nearly every part of our bodies, including our inner ears which allow us to hear. Some medications alone are not ototoxic; however, when taken at the same time with another drug they can become ototoxic. Smoking, lack of exercise and a diet lacking substantial nutrients can all contribute to hearing loss. These highly trained and certified professionals will perform a top-down hearing evaluation to determine the scope and degree of hearing loss you have. In most cases, a pair of hearing aids will get you back in the game and keep you in play longer.
And although cost is typically a high priority, try not to make it your number one consideration. Together, your audiologist or hearing aid dispenser will develop a strategy that suits your hearing needs and personal preferences. The design and cosmetic appeal coupled with outstanding sound quality and automated convenience are helping those with hearing loss hear the sweet sounds they have been missing. However, two tuning fork tests—the Rinne and Weber—have stood the test of time and retain their importance for clinicians in diagnosing hearing loss. In this paper, we review the basic principles involved in the use, theory, and interpretation of the Rinne and the Weber. Michael Hall, AuD, is a clinical audiologist who lives in Walnut Creek, Calif, and is now retired from private practice.
Although there are quite a few TFTs that were developed prior to the widespread use of audiometers, TFTs other than the Weber and Rinne are not of the same clinical value they were prior to the introduction of audiometers and immittance bridges. He and other researchers did an excellent job explaining the rationale for 512 Hz and 1024 Hz as the preferred frequencies for administering the Weber and Rinne.


The rationale for using lower frequencies is that the tuning fork is more subtle in terms of identifying conductive hearing loss at these frequencies. The factors that explain why the fork lateralizes to the ear with a conductive pathology when the other ear is normal or has some degree of sensorineural hearing loss are the same four primary factors previously noted for BC: middle ear inertia, middle ear compliance, inner ear compression, and round window release.
Technically, 500 Hz means a 500 Hz tone via the audiometer’s bone oscillator, while 512 Hz is the tuning fork frequency. A useful method of recording the results of TFT is shown in Figure 1 where the Latin origin of these letters is defined. If a conductive loss is present in only one ear and the other ear has a sensorineural loss, the patient will still report the fork being louder in the ear with the middle ear pathology. The tuning fork tines are put into vibration in the same manner as when conducting the Weber Test.
Audiometric puretone and tuning fork test results for a patient with a unilateral mixed hearing loss.
Audiometric puretone and tuning fork test results for a patient with a bilateral sensorineural hearing loss. These tests, in our opinion, offer support to more modern audiometric tests in assisting all professionals involved in administering hearing tests.
This may be useful, for example, in cases of conductive hearing loss with normal tympanograms where an air-bone gap is present on the audiogram, but the patient does not have otitis media. The length of the rod allows the tuning of it, a sound very similar to a human whistle but with a lot of manipulation.
Unfortunately, many of us recognize that we don’t hear as well as we did in years past but accept hearing loss as inevitable. Ensure you always manage your prescriptions at one pharmacy so the pharmacist can warn you on any potential side effects of multiple prescriptions. If they suspect an underlying medical condition contributing to your hearing loss, they will refer you to yoru family physician or an Otolaryngologist - a physician specialing in ears and hearing. This results in a comfortable and more natural feeling hearing aid in regards to both sound and physical feel. Thank you to miniaturization of digital hearing aid parts and new innovative designs, today’s BTEs are not the type grandpa used to wear.
No longer are they beige and boring, they’re fashion statements that also improve your hearing. We will also provide a discussion of how to interpret the results, as well as the AC and BC phenomenon that determines the various results seen with these two tests. Carl Croutch, AuD, is an audiologist at Kaiser Permanente Hearing Center in Daly City, Calif. For example, at frequencies 2 to 3 octaves lower than 2000 Hz, an air-bone gap one-half or less the size than at 2000 Hz is typically needed to indicate a conductive loss. The effect of all of these various components results in producing in-phase and out-of-phase traveling waves in the cochlea.11 The in-phase condition results in an increase in amplitude, which creates a perception that the Weber is louder in the ear with the middle ear pathology. The stem is placed on the mastoid prominence on one side, and then transferred to the opening of the same ear while keeping the tuning fork from actually touching the patient’s ear. Looking at Figure 1 will acquaint the reader to a quick and easy method to report TFT results. When conducting the Rinne, where there is a 30 dB or more difference between ears, it is advised to mask the better ear when conducting the test. In fact according to the National Institute of Deafness and Other Communication Disorders, 1 in 3 Americans over the age of 65 have some degree of hearing loss. And notify ALL your doctors about ALL of your prescriptions – especially ones prescribed by a different physician. In fact, medics in war zones now carry medications that are administered to soldiers who are exposed to loud, concussive explosions. When middle ear pathologies are present, there is an increase in impedance at the footplate and oval window, which create in- and out-of-phase traveling waves in the cochlea.
When the middle ears are normal, the Weber lateralizes to the better cochlea simply because it is the better-hearing ear. Normally, we instruct the patient that they will hear two sounds: one at the bone behind their ear and the other in their ear.
If the patient’s hearing loss is severe, the clinician may rely on sign signals such as having the patient hold up one or two fingers to indicate which sound is the loudest.
The sooner these meds are given after exposure to an explosion, the more likely hearing returns to the normal range, though there’s no hard and fast rule. Today’s hearing aids come in a range of styles, types, colors and profiles, one of which is sure to suit your needs and preferences. The patient will report they either cannot tell if it is louder in one ear or the other, or will report hearing it at their forehead. They are cautioned not to think about what the correct answer should be, but to merely say whether number 1 (mastoid prominence) or number 2 (the opening of the ear) is louder. However, in a severe loss with no conductive component present, it is unlikely the tuning fork will be heard. 689-692 (1962)A Human Perception of Illumination with Pulsed Ultrahigh-Frequency Electromagnetic Energyby Allan Frey, Science, Vol. Baker, Youth Action Newsletter, Dec 1994.A "A nation can survive its' fools, and even the ambitious. An enemy at the gates is less formidable, for he is known and he carries his banners openly. But the traitor moves among those within the gate freely, his sly whispers rustling through all the galleys, heard in the very hall of government itself. For the traitor appears not a traitor--He speaks in the accents familiar to his victims, and wears their face and their garment, and he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation--he works secretly and unknown in the night to undermine the pillars of a city--he infects the body politic so that it can no longer resist.
The CIA also claims it is not obligated to provide the veterans with medical care for side effects of the drugs. Its the CIAs third attempt to get the case dismissed.In a 2009 federal lawsuit, Vietnam Veterans of America claimed that the Army and CIA had used at least 7,800 soldiers as guinea pigs in Project Paperclip. They were given at least 250 and as many as 400 types of drugs, among them sarin, one of the most deadly drugs known to man, amphetamines, barbiturates, mustard gas, phosgene gas and LSD.Among the projects goals were to control human behavior, develop drugs that would cause confusion, promote weakness or temporarily cause loss of hearing or vision, create a drug to induce hypnosis and identify drugs that could enhance a persons ability to withstand torture.
The suit was filed in federal court in San Francisco against the Department of Defense and the CIA. The plaintiffs seek to force the government to contact all the subjects of the experiments and give them proper health care. Department of Veterans Affairs released a pamphlet said nearly 7,000 soldiers had been involved and more than 250 chemicals used on them, including hallucinogens such as LSD and PCP as well as biological and chemical agents. According to the lawsuit, some of the volunteers were even implanted with electrical devices in an effort to control their behavior. Rochelle, 60, who has come back to live in Onslow County, said in an interview Saturday that there were about two dozen volunteers when he was taken to Edgewood.
They were told that the experiments were harmless and that their health would be carefully monitored, not just during the tests but afterward, too. The doctors running the experiments, though, couldnt have known the drugs were safe, because safety was one of the things they were trying to find out, Rochelle said. The veterans say they volunteered for military experiments as part of a wide-ranging program started in the 1950s to test nerve agents, biological weapons and mind-control techniques, but were not properly informed of the nature of the experiments.


They blame the experiments for poor health and are demanding the government provide their health care.
In virtually all cases, troops served in the same capacity as laboratory rats or guinea pigs, the lawsuit states.
The suit contends that veterans were wrongfully used as test subjects in experiments such as MK-ULTRA, a CIA project from the 1950s and 60s that involved brainwashing and administering experimental drugs like LSD to unsuspecting individuals.
The project was the target of several congressional inquiries in the 1970s and was tied to at least one death. Harf said that MK-ULTRA was thoroughly investigated and the CIA fully cooperated with each of the investigations. The plaintiffs say many of the volunteers records have been destroyed or remain sealed as top secret documents. They also say they were denied medals and other citations they were promised for participating in the experiments.
They are not seeking monetary damages but have demanded access to health care for veterans they say were turned away at Department of Veterans Affairs facilities because they could not prove their ailments were related to their military service. It grew out of the Agencys Operation BLACKBIRD and was a forerunner to the Agencys MKULTRA. Project ARTICHOKE also known as Operation ARTICHOKE was run by the CIAs Office of Scientific Intelligence.
ARTICHOKE offensive mind control techniques experiments attempted to induce amnesia and highly suggestive states in its subjects. ARTICHOKE focused on the use of hypnosis, forced morphine addiction, forced morphine addiction withdrawal, along with other drugs, chemicals, and techniques.
The main focus of the program was summarized in a January 1952 CIA memo, Can we get control of an individual to the point where he will do our bidding against his will and even against fundamental laws of nature, such as self-preservation?One program experiment attempted to see if it was possible to produce a Manchurian Candidate. In Richard Condons 1959 novel The Manchurian Candidate an American soldier, who has been placed into a hypnotic state by Communist forces, returns home to assassinate on command. A January 1954 CIA report asks the question, Can an individual of [redacted] descent be made to perform an act of attempted assassination involuntarily under the influence of ARTICHOKE?
Argued December 4, 1984 Decided April 16, 1985 .Between 1953 and 1966, the Central Intelligence Agency financed a wide-ranging project, code-named MKULTRA, concerned with the research and development of chemical, biological, and radiological materials capable of employment in clandestine operations to control human behavior. 159, 162] program consisted of some 149 subprojects which the Agency contracted out to various universities, research foundations, and similar institutions. Because the Agency funded MKULTRA indirectly, many of the participating individuals were unaware that they were dealing with the Agency.MKULTRA was established to counter perceived Soviet and Chinese advances in brainwashing and interrogation techniques. Over the years the program included various medical and psychological experiments, some of which led to untoward results. These aspects of MKULTRA surfaced publicly during the 1970's and became the subject of executive and congressional investigations.
Argued April 21, 1987 Decided June 25, 1987 Respondent, a serviceman, volunteered for what was ostensibly a chemical warfare testing program, but in which he was secretly administered lysergic acid diethylamide (LSD) pursuant to an Army plan to test the effects of the drug on human subjects, whereby he suffered severe personality changes that led to his discharge and the dissolution of his marriage. Upon being informed by the Army that he had been given LSD, respondent filed a Federal Tort Claims Act (FTCA) suit. The District Court granted the Government summary judgment on the ground that the suit was barred by the doctrine of Feres v.
135 , which precludes governmental FTCA liability for injuries to servicemen resulting from activity incident to service. Although agreeing with this holding, the Court of Appeals remanded the case upon concluding that respondent had at least a colorable constitutional claim under the doctrine of Bivens v. 388 , whereby a violation of constitutional rights can give rise to a damages action against the offending federal officials even in the absence of a statute authorizing such relief, unless there are special factors counselling hesitation or an explicit congressional declaration of another, exclusive remedy.
Respondent then amended his complaint to add Bivens claims and attempted to resurrect his FTCA claim. Although dismissing the latter claim, the District Court refused to dismiss the Bivens claims, rejecting, inter alia, the Governments argument that the same considerations giving rise to the Feres doctrine should constitute special factors barring a Bivens action.In February 1958, James B. Stanley, a master sergeant in the Army stationed at Fort Knox, Kentucky, volunteered to participate in a program ostensibly designed to test the effectiveness of protective clothing and equipment as defenses against chemical warfare. He was released from his then-current duties and went to the Armys Chemical Warfare Laboratories at the Aberdeen Proving Grounds in Maryland. Four times that month, Stanley was secretly administered doses of lysergic acid diethylamide (LSD), pursuant to an Army plan to study the effects of the drug on human subjects.
According to his Second Amended Complaint (the allegations of which we accept for purposes of this decision), as a result of the LSD exposure, Stanley has suffered from hallucinations and periods of incoherence and memory loss, was impaired in his military performance, and would on occasion awake from sleep at night and, without reason, violently beat his wife and children, later being unable to recall the entire incident.
One year later, his marriage dissolved because of the personality changes wrought by the LSD. December 10, 1975, the Army sent Stanley a letter soliciting his cooperation in a study of the long-term effects of LSD on volunteers who participated in the 1958 tests. 669, 672] This was the Governments first notification to Stanley that he had been given LSD during his time in Maryland. 2671 et seq., alleging negligence in the administration, supervision, and subsequent monitoring of the drug testing program. Ewen Cameron): The man who I had thought cared about what happened to me didnt give a damn. Ewen Cameron conducted CIA-funded experiments on troubled Canadian patients he was meant to help MacIntyre: the CIA caved in the day before the trial was to begin.
They settled out of court for $750,000 at the time it was the largest settlement the CIA had ever awarded.
28, 1984 (digital clip) It sounds like a science fiction plot or a horror movie: A front organization for the American CIA sets up shop in Canada to engage in mind control experiments. But its no fiction, its the discussion on the floor of the House of Commons and among lawyers for the Department of External Affairs.
Canadians caught up in the research, including a member of Parliaments wife, may finally get some action from the government in their pursuit of answers and compensation. Recruited Ex-Nazis By SAM ROBERTS December 11, 2010 After World War II, American counterintelligence recruited former Gestapo officers, SS veterans and Nazi collaborators to an even greater extent than had been previously disclosed and helped many of them avoid prosecution or looked the other way when they escaped, according to thousands of newly declassified documents. Men who were classified as ardent Nazis were chosen just weeks after Hitlers defeat to become respectable U.S. Reinhard Gehlen (middle) and his SS united were hired, and swiftly became agents of the CIA when they revealed their massive records on the Soviet Union to the US. The men designed the CIAs interrogation program and also personally took part in the waterboarding sessions. But to do the job, the CIA had to promise to cover at least $5 million in legal fees for them in case there was trouble down the road, former U.S. For the simple reason that it would inexorably lead to the covert biological war programmes of the 1950's. According to CIA documents, K indicates both knockout and kill, depending upon the circumstances under which researched biological products were employed by CIA operatives in the field operations conducted under Project Artichoke and later programs.
