Teaching about hearing can save young people’s ears

06.03.2012
Many adolescents frequently expose their ears to loud sounds, for example from portable music players.

Some of them may think that ‘the doctor said that my hearing is good, so I guess I can handle the loud volume’. A new doctoral thesis from the University of Gothenburg, Sweden, shows that research-based teaching in school can be used to positively change adolescents’ awareness and behaviour.

Eva West, researcher at the Department of Pedagogical, Curricular and Professional Studies, has developed research-based teaching material about sound, hearing and auditory health that she has tested on nearly 200 students in grades 4-8. The students’ knowledge about sound, the function of the ear, hearing and tinnitus was tested before and after the teaching. She also studied the students’ attitudes towards high sound levels.

Challenging for students

The results show that it was challenging for the students to understand the concept of sound and sound transmission due to its abstract nature. Students tend to think of sound as a material phenomenon and not as what it really is: a movement that is transmitted. They for example think that sounds occur when material sound waves collide with the components of air, when in fact material sound waves do not even exist.

‘A teacher who is aware of this perception and who repeatedly assesses the students’ knowledge can plan the teaching accordingly, and thus improve the learning process,’ says Eva West.

Tinnitus

Five percent of the students indicate that they are often bothered by tinnitus. As many as 35-70 percent, depending on the age of the students, say that they have experienced tinnitus at some point. A majority of the students knew very little about the function of the ear before the teaching, which means that their understanding of the importance of taking good care of one’s hearing was limited.

‘Teaching young people about how hearing works and that there are small hair cells that we need to be careful with may help them better understand messages such as “Be careful with your hearing”,’ says West.

Her results show that the students’ attitudes towards sound levels and hearing were healthier after than before the teaching, and there were also signs that their behaviour changed in a healthy direction.

The thesis was successfully defended on Friday 20 January.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
