Several factors can result in loss of hearing
By JOHN HENDEL
Staff Writer
Normal classroom noise may be loud enough to interfere with a person's ability to hear speech clearly, but won't cause permanent damage, according to C. P. Goetzinger, chief of audiology at the University of Kansas Medical Center.
This interference with noise discrimination, a person's ability to hear speech clearly is only part of the problem of hearing loss.
June Miller, chairman of the hearing and speech department at the Med Center, said yesterday that hearing loss was such a big problem that there were a number of research projects investigating the premature loss of hearing acuity.
Certain people are more susceptible to hearing loss, she said, but it can happen to many.
Developer Luoper Burzi of Mark I inc.
yesterday withdrew his request to move 27 apartment units from the southeast corner
of the development to the northwest corner.
The commission was to have reconsidered the requested change. It had voted 3 to 2 last week to approve the change, but a protest petition filed by residents within 200 feet of the affected area required a 4 to 1 vote to approve the change.
Commissioners Carl Milek and Donald Binns, who voted against the change last week, said they would have opposed it again. Thus, the change would have been denied.
Residents of the area claimed they had a sufficient number of names on the petition when the commission voted last Tuesday, but Dick McClanathan, city planner, said there weren't enough names on the petition til Wednesday.
A request to change the plan of the Heatherwood Planned Unit Development (PUD) didn't quite make it to last night's Lawrence City Commission meeting.
Heatherwood, at 23rd and Kasafi streets,
includes plans for a variety of single-family,
and two-family homes.
The commission last night discussed a suggestion of Buzi that the northwest

However, commissioner Fred Pence said the city couldn't afford to spend more than $5 billion annually.
Someone suggested just leaving it as an open area.

Goettinger said there were a number of factors that caused hearing loss. Those factors include heredity, some injuries such as trauma and excessive noise.
Another cause of hearing loss, he said, some diseases such as measles and pneumonia.
No action was taken.
John Brandt, associate professor of speech and drama, said that a vascular problem could also cause a hearing loss. He added that he had no blood supply to the auditory nerve, could result in complete hearing loss in one or both ears. Brandt said that this problem wasn't an inherent weakness in the person, but it was something that could happen to anyone.
He said the primary causes of premature hearing loss around this part of the country were loud rock music and gunshots when hunting.
"High intensity noise is transmitted to the inner ear, and this physically destroy the sensory cells, Branda said. "High intensity noise is also destroyed that are destroyed they can't be repaired."
Miller said loudness was relative to the person. What may be loud to one person is much less to another, though both persons have normal hearing. Brandt agreed saying that this difference

Brandt said age was a problem because old people were unable to recuperate as adults.
Goetzinger said hearing loss usually occurred in the 90 decibel db range. The average car generates about 65 db on the highway.
lower than 19 db, but this damage is slight and healing takes place in a relatively short period.
Goetginger said some rock bands have been measured at the 110-121 db range. The amount of damage done by this high deibel count depends on the amount of exposure.

Exposure for a few minutes may show no hearing loss, he said, but exposure to loud music for any length of time can cause an acute hearing loss.
