Section 1. Case

The World Health organization (WHO) declares more than 10% of people

on the Earth suffers with different hearing impairs. Students with hearing

impairs often have certain difficulties while class trainings, especially if they

do not use special hearing aids. Either many students don’t use special

devices due to medical recommendations or having scruples (the last

reason is for youths mostly).

Lifelong learning becomes the MUST for almost each person, and different

educational organizations offers virtual courses and trainings in different

modes: e-learning, webinars, blended.

The task is to involve people with hearing impairs into active lifelong

learning process.

Section 2. Concept

The ITFORYOU company builds a strong team of scientists, engineers,

programmers and learning specialists to deliver a special technology

(named and patented as Petralex) to improve quality of life for people

with hearing impairs. The Petralex is a set of mobile Apps and Windows

drivers, which work as a personal hearing assistant (see www.petralex.pro).

A student passes a simple hearing test (in situ), and the application creates

a set of his/her own profiles according to different environment (for

example, street, home, classroom, work area, etc.).

Fig. 1. The Petralex App

The Petralex driver creates a Virtual audio device (VAD), which adjusts

audio level at each frequency according to personal hearing profile and

surrounding noises.

A user (a student, for example) has an opportunity for comfortable and

hearing protected way to listen to an audio/video recording, or participate

in an on-line training.

Section 3. Partner Model and Lead

The ITFORYOU offers social partnership to all types of educational

organizations: high schools, universities, professional and lifelong training

centers.

Offer your students with hearing impairs download and use the Petralex

iOS/Android App or Windows driver.

We can adapt the the Petralex App/driver to partner design (chargeable).

Your educational organization/training center expands audience by

involving students with hearing impairs into virtual learning process (all

types: on-line, blended and off-line e-learning).

Together we make the world friendlier for people with hearing impairs!

Section 3.1. Success story

The Petralex had been implemented first in a partner project with

the Specialist training center (the leading computer training center

www.iamcp.org

in CEE region), and won the first prize by LERN (Learning Resources

Network, www.lern.org) in 2015 as the best solution for lifelong learning

Section 4. Implementation model A. Typical learning cases for on-line trainings.

A student can study for a long time due to improved hearing tolerance, reducing fatigue for long listening sessions, and attenuation of excessive sound pressure (fig. 2). While training sessions we recommend students actively collaborate with a trainer, their classmates, as well as with other webinar colleagues.

1. A teacher explains learning materials, for example a theory. A student studies at home. S(h)e activates “home” profile, and can hear a teacher clearly. In case of misunderstanding, a student asks questions in the same manner as his/her classmates, and does not go behind the class.

2. A business or other role game. For example, our student plays a role of a virtual team member. S(h)e collaborates both with mates in class and/or online using VAD for better hearing mates. The virtual team plays its role, and all students get practical skills.

3. Presenting an individual work, exercise. A student can present a work by means of an appropriate software tools (e.g. Skype, Citrix, WebEx, etc.), and discuss it with a teacher and classmates.

B. Asynchronous learning methods

Second, let us consider learning scenarios for asynchronous learning methods. Asynchronous learning includes such tools as learning management systems (LMS), stream and offline video, audio, podcasts.

As shown at fig. 2, audio signal inputs through the VAD, which transforms it according to an activated user hearing profile. A student can tale his/her studies at various locations, for example, we tested scenarios:

In a special class,

At home

At a workplace

On a beach.

A student takes studies in a blended format at a special class. We implement so-called “open classes” training method. Students in a common class study different courses under a teacher supervision. Each student can use the VAD with the Petralex driver to make hearing to video and audio recordings comfortable and decrease surrounding noises.

At home, a student can study video and audio training records using headsets at a comfortable level for a long time, and do not disturb a family with loud sound.

One of the most impressive cases in our practice is short-term learning for busy people during vacations or weekend. An adult student may combine a rest and studies. For example, a student creates a “beach” profile, and can listen learning records on a comfortable manner for his/her hearing.
