Audio material facilitating the preparation to explore an unknown environment by persons with visual impairments

Summary/Abstract: In Poland, the number of people with visual impairment (damage and disease of the visual organ), including legal disabilities and those who declare that they have limitations in carrying out normal activities is 1/3 of the total population. It is well known that the hearing plays an important role in the functioning of people with visual impairment. At the same time, these people are often afraid of leaving their well-known environment, such as their homes. It would be important for people with visual impairment to become familiar with surrounding sounds that they might encounter in an external environment. During the research carried out in CIOP-PIB a set of sounds has been collected that can be used by people with visual impairment to familiarize with the environment to which they can potentially go. The Ambisonics technique was used and sounds were binaurally recorded with the use of microphones built into the headset. These solutions allowed to obtain the spatial impression associated with the correct direction of the sound. The audio material includes a number of situations in which a person with a visual impairment could potentially be found, recorded not only at home but also, for example, near junctions or in office buildings. Necessary data conversions were used to obtain files in a format that could be played back over headphones connected to a PC. The data obtained is intended for use in the software familiarizing people with visual impairment with potentially new situations for them.
