In addition to the convenient carrying case, you will also find a cool Alpine Miniboxx in each PartyPlug packaging. Through pure-tone audiometry, we studied the course of hearing recovery in 24 ears of 20 men (ages 18-48 years) who had acute acoustic sensorineural hearing loss (ASHL).
Acute acoustic sensorineural hearing loss (ASHL) caused by exposure to extremely loud noises, such as gunshots, and associated with subsequent hearing loss and ear ringing is infrequently encountered in general practice.
Detailed examination of the course of hearing recovery in patients with acute ASHL may improve the accuracy of prognosis.
We graphically depicted the time course of recovery of pure-tone hearing by plotting the number of days after noise exposure on the horizontal axis and the hearing level on the vertical axis.
Among our patients with acute ASHL, evaluation revealed cure in 5 ears, recovery in 13 ears, and unchanged status in 6 ears. A 19-year-old patient experienced ringing in the left ear and hearing loss after shooting a rifle without earplugs on July 29, 1999. The patient's hearing improved gradually, but a puretone audiometric examination on August 5 revealed that hearing levels at 2,000 and 4,000 Hz had not returned to normal. A 22-year-old patient experienced ringing in his right ear after shooting a rifle without earplugs on the night of July 8, 2003. A 43-year-old man experienced ringing in his right ear and a feeling of ear closure after shooting a rifle without earplugs on June 12, 2000. A 23-year-old patient experienced ringing and hearing loss in both ears because his earplugs were dislodged when he had shot a rifle on March 3, 2005. A 23-year-old patient experienced ringing in his left ear after shooting a rifle without earplugs on November 27, 2004. A 19-year-old man experienced hearing loss in the left ear and ear ringing after shooting a machine gun without earplugs on August 3, 1998. Those patients in the cured group were younger (mean age, 20.2 years) than those in the other groups and were treated soon after injury (on average, 3 days after noise exposure). A 38-year-old patient experienced a sensation of left-ear obstruction on awakening on the morning of August 16, 2003.
Pilgramm [4] suggested that in rifle-related injuries, the right ear sustains minimal damage because it is protected by the right forearm, shoulder, and gunstock. In the unchanged group, all patients had hearing loss at 4,000 and 8,000 Hz at presentation. Experimental studies of ASHL in monkeys and chinchillas reported that sensory cells (hair cells) in the basal turn are damaged up to several millimeters from the cochlear window [5,6]. Transmission electron microscopical studies by Libermann and Dodds [9] have shown that shortening of basal rootlets in the cuticula plate in stereocilia initially causes a TTS. At the frequency range of 3,000-6,000 Hz, the operating area of the basal plate in the human cochlea is considered to lie at the junction between the proper cochlear artery and the cochlear branch of the vestibulocochlear artery.
Our results indicate that extremely loud noise caused the microangiopathic and organic disturbances in the cochlea, irrespective of noise frequency. Unlike the outcome in ASHL, in which only the hearing level at 4,000 Hz did not readily return to normal, hearing levels at all frequencies in patients with sudden hearing loss did not return to normal.
In conclusion, our results suggest that hearing in patients with acute ASHL is likely to return to normal when the hearing level at 4,000 Hz show signs of gradual improvement.
The loud music and the shouting in each other’s ears to be heard, simply was too much.
The extremely well thought-out and extensively tested shape of the earplugs, provides a natural flat absorption and a great fit.
This material takes on the shape of the air, giving the earplugs a perfect fit in the hearing canal, allowing them to stay put in the air, making them feel extremely comfortable.
This convenient carrying case is easy to take with you when going out and can be opened with one hand. Course of Hearing Recovery According to Frequency in Patients with Acute Acoustic Sensorineural Hearing Loss.
Because early initiation of treatment may improve or cure such hearing loss, prompt diagnosis and appropriate therapy are imperative [1,2]. However, few studies have evaluated the process leading to recovery of hearing in such patients.
Six patients were in their teens, nine were in their twenties, one was in his thirties, and four were in their forties.


The results of pure-tone audiometry at presentation are shown as overlapping audiograms by group-cured, recovered, and unchanged (Fig. The course of recovery of pure-tone hearing in patients with acute acoustic sensorineural hearing loss. He was examined on the same day and was admitted to the hospital because we diagnosed moderate, gradual high-tone sensorineural hearing loss.
We diagnosed abrupt high-tone sensorineural hearing loss (from 2,000 Hz) at presentation on July 9. At presentation the next day, we diagnosed abrupt high-tone sensorineural hearing loss (shown from 2,000 Hz).
At presentation the next day, we diagnosed moderate, gradual hightone sensorineural hearing loss (from 1,000 Hz), and he was admitted to the hospital. Hearing levels at 125-500 Hz returned to normal in all ears, but the hearing level at 4,000 Hz did not improve in 12 of 13 ears. The course of recovery of pure-tone hearing in two patients from the recovered group is shown in Figure 3. She was examined the next day and was given a diagnosis of sensorineural hearing loss with a flat audiometric pattern (mean hearing level in the left ear, 80 dB HL). Unlike the action in acute ASHL, hearing levels at some frequencies other than 4,000 Hz did not recover to normal.
We examined the time course of hearing recovery by means of pure-tone audiometry in 20 patients with acute ASHL.
However, we found at presentation no significant difference in pure-tone hearing at any frequency among patients in the cured, recovered, and unchanged groups (analysis of variance). However, no significant difference between the recovered and cured groups was seen in the time until the start of treatment. The vascular changes described earlier and hemodynamic disturbances usually occur at the end of this bifurcation, leading to a dip at 4,000 Hz and delayed recovery of hearing level. Reversible disturbances resolved gradually, but damage in the operating area around 4,000 Hz was irreversible and persisted. The cause of sudden hearing loss is unknown but may be associated with many factors, such as viral infection, circulatory disturbances in the inner ear, rhexis of the membranous labyrinth, and metabolic disorders. In contrast, only partial recovery is likely when the hearing level at 4,000 Hz reaches an early plateau. When this happens more often, there is a serious risk of permanent hearing loss and permanent ringing ears.
The hearing level in 5 ears returned to normal, the hearing level of 13 ears recovered but was not within the normal range, and the hearing level of 6 ears was unchanged. We studied the time course of recovery of puretone hearing in members of the Japanese Self-Defense Force who had acute ASHL caused by shooting guns.
The time course of recovery of pure-tone hearing was graphically depicted by plotting the number of days after noise exposure on the horizontal axis and the hearing level on the vertical axis (two patients from each group).
Vasodilators and steroids were given by continuous intravenous infusion, and vitamin B12 was given orally. Vasodilators were given by continuous intravenous infusion, and steroids were given orally.
Those in the unchanged group were older (mean age, 28.6 years) than those in the cured group, and the time from noise exposure to presentation was longer in the unchanged group (mean, 48 days) than in the cured group.
As a control, we compared the time course of hearing recovery in our patients who had sudden hearing loss and were treated between 1991 and 1997 (two patients from the recovered group).
Sensorineural hearing loss with a flat audiometric pattern (mean hearing level, 85 dB HL) was diagnosed by quartering.
We treated her on an outpatient basis and administered steroids with stellate ganglion blockade. The outcome in our patients was registered as cured in 5 ears (21%), recovered in 13 (54%), and unchanged in 6 (25%). Hearing level at 500 Hz or less returned to normal in all 13 ears, but hearing level at 4,000 Hz returned to normal in only 1 of 13 ears. These findings could explain the audiometric pattern at presentation (c5dip) and the abrupt onset of high-tone sensorineural hearing loss. Hawkins [10] studied the effects of extremely loud noise on endocochlear direct current potential, which occurs in vascular stria cells.


However, those authors measured the mean hearing level and did not evaluate changes in hearing levels at different frequencies.
Patients who seek medical attention 14 days or more after noise exposure may have fixed hearing levels that are unlikely to recover to normal.
Prognosis of acute acoustic trauma: A retrospective study using logistic regression analysis. Acute ultrastructural changes in acoustic trauma: Serial section reconstruction of stereocilia and cuticular plates. The time from noise exposure to presentation was longer in patients with unchanged hearing than in other patients. We confirmed by interview that all patients had shot guns and had no history of ear diseases, such as acoustic trauma or hearing loss. An audiometric examination on July 12 showed that the hearing level had returned to normal.
Pure-tone hearing was unchanged despite the continuous intravenous infusion of vasodilators and steroids. The patients in the recovered group were older (mean age, 28.2 years) than those in the cured group. Hearing at 125 and 250 Hz returned to normal on September 10, and hearing at the other frequencies improved slightly. Disturbances of pure-tone hearing were cured in approximately 20% of our patients and recovered partially in 75%. The reason for the absence of significant difference in hearing level at presentation may be the small size of the cured group (five patients).
Hearing level at 4,000 Hz reached a plateau after approximately 7 days of treatment and did not return to normal in most patients. In the unchanged group, some patients' hearing may have recovered somewhat during the period from noise exposure to presentation.
He reported that extremely loud noise causes vasoconstriction, irrespective of noise frequency. Pure-tone audiometric examinations revealed that hearing levels at all frequencies were within normal range (25 dB HL or less) in the unaffected ear.
However, the hearing level at 4,000 Hz did not improve in either ear after 7 or more days of treatment; hearing loss persisted. There was no difference in the time from noise exposure to the start of treatment (mean, 4 days) between the recovered group and the cured group. Hearing loss at 4,000 and 8,000 Hz was noted at presentation in all patients in the cured group and did not respond to treatment.
Those in the cured group were younger, and the time until the start of treatment was shorter (mean, 3 days) than in the other groups.
Hearing at frequencies other than 4,000 Hz may have undergone a temporary threshold shift (TTS), whereas that at 4,000 Hz may have undergone a permanent threshold shift (PTS).
We concluded that hearing in patients with acute ASHL is likely to return to normal when the hearing level at 4,000 Hz recovers gradually; partial recovery of hearing is expected when the hearing level at 4,000 Hz reaches an early plateau. The causes of hearing loss were gunshots from a rifle in 18 patients, a machine gun in 1, and an air gun in 1. Puretone hearing levels at 2,000 and 8,000 Hz returned to normal in some patients whose presentation hearing levels at 2,000 and 8,000 Hz were worse than that at 4,000 Hz. With the exception of those in the cured group, recovery of hearing level was poorest at 4,000 Hz, followed by 8,000 and 2,000 Hz. Thus, the presence of severe hearing loss at 4,000 Hz is not likely responsible for the poor response at this frequency. Standard therapy for sudden hearing loss, including adrenocortical hormones (prednisolone, 60 mg), vasodilators (10% low-molecular-weight dextran, 500 ml), and vitamin B 12 (1,500  g), was given to the patients from the day of presentation.
