    Opis:
    Elaboration of a new method of teaching spatial orientation to blind and visually handicapped persons base on urban environment sounds was shown. Task 1 is a questionnaire inquiry on the problems of the blind moving in a big city. In Task 2 a preliminary selection and classification of the acoustic signals and vibrations that can be useful for spatial orientation was made. In Task 3 an analysis of acoustic signals for sound signalisation at pedestrian crossings was made. Some solutions for acoustic signalization were proposed. In Task 4 sounds and vibrations necessary for a library of acoustic events and situations characteristic of a city were recorded. In Task 5 the library was created and arranged to be ready to be used by teachers in the spatial orientation training. The most important outcome of the study was to develop a method of spatial orientation teaching with employment of sounds and verification of the method (Task 6). After verification it is concluded that the method is useful for spatial education of the blind at different levels of their education.

    Opis:
    The paper presents a psychoacoustical evaluation of selected acoustic signals, which according to Polish and international recommendations can be applied at pedestrian crosswalks. The aim of the study was the optimal adjustment of parameters of the signals emitted at pedestrian crosswalks, and to meet the expectations of persons with vision impairments as well as nearby residents or workers working near the crossing. The psychoacoustical evaluation of acoustic signals consists of determination of the hearing threshold of signals in the quiet, detection of signals presented against a background of various types of traffic noises (estimated signal-to-noise ratio) and annoyance assessment of signals. Three types of intermittent sounds were analysed: signals with rectangular time pattern filled up with rectangular wave, signals with rectangular time pattern filled up with sinusoidal wave and signals with triangular time pattern filled up with sinusoidal wave. Four fundamental frequencies (550 Hz, 880 Hz, 1580 Hz and 2000 Hz) and two repetition rates (5 Hz and 9 Hz) were tested. The results of the study have shown that the most suitable signals which can be applied at pedestrian crosswalks are the intermittent sounds with rectangular time pattern filled up with rectangular wave of fundamental frequencies 880 Hz and 1580 Hz and repetition rate 5 Hz and the intermittent sounds with rectangular time pattern and triangular time pattern both filled up with sinusoidal wave of fundamental frequencies 1580 Hz and repetition rate 5 Hz.

    Results of an auditory training for blind/visually impaired children and teenagers are presented. A measure of the training effectiveness is the difference between the results of a pre- and post-training verification test. Two age groups of visually handicapped young persons were tested: 7-12 years old and 14-19 years old. It was shown that the training may be beneficiary for blind or visually impaired children and teenagers, especially in tasks related to localization of moving sound sources. No differences in training results were found between age groups. The results of trained groups were compared to those obtained for not trained control groups of young blind individuals.

    Opis:
    Performance of blind/visually impaired children and teenagers before and after the auditory training and the music training in some auditory tasks (pitch discrimination, pitch-timbre categorization, pitch memory, lateralization of a stationary sound of a drum, lateralization of one or two moving motor vehicles) is compared. In the auditory training, the subjects were actively involved, i.e. they had to answer questions related to presented sound material. The music training was based on passive listening to sounds presented according to the Tomatis method. The training (auditory or music) effectiveness was measured as a difference between results of a pre- and post-training verification test in which the subjects were asked to perform the auditory tasks mentioned at the beginning. The persons who took part in the study were divided into two age groups: 7-12 year olds and 13-19 year olds. According to the results, the auditory training was beneficial for blind or visually impaired teenagers, especially in respect of lateralization tasks. For small children the auditory training was not as effective as for adolescents. However, it has been shown that the music training was generally beneficial for them, although none of the verification tasks was privileged.
