It is a Take-home CD
running on MS Windows 2000 and higher and requires a loudspeaker with a volume control. The objective of the CD is to increase attention to and identification of targeted sounds
in quiet and in noise and is for adult use only.
There is directed listening to voiceless consonant
sounds / p, t, k, s, f, Ө, ∫, t∫ / and all vowels.
The CD is not targeted at specific auditory skills such as auditory closure, etc (but hopefully attention, discrimination and memory skills are heightened)
It does have an option to perform training in variable noise backgrounds.
It is appropriate for anyone with a hearing loss, but especially ideal for those with a sloping high frequency loss. (Adults Only)
Each CD (There are 2: a vowel CD and a consonant CD) is a 10-day, 20-30 min training. The materials are read by three speakers (2 females & one male).NOTE: Not meant to replace commercial materials; NOT VALIDATED
