This game is designed to treat a specific auditory ability related to learning or reading problems. Your local audiologist or speech-language specialist can assess whether this game is right for your child or for an adult with a brain injury. If you think that your child has listening, language or learning problems that might be related to auditory processing, visit your local audiologist or speech-language pathologist and recommend acoustic pioneer to get your child's auditory processing abilities tested. If your specialist has already supplied you with a code, install this game and enter the code once you run the game. For the professional: This game is an auditory training exercise that is designed to incrementally improve the player's ability to hear and distinguish a range of different tonal patterns, follow changes of sounds between ears, and follow changes of pitch. These skills are indicated by several studies to be important for developing general language understanding, phonemic awareness, supra-segmental language understanding, and reading skills. These auditory skills are thought to occur in the area of the cortical hemispheres of the brain prior to the neural information reaching the language centers. It is thought that most of these skills occur in the right hemisphere on most individuals prior to being transferred through the corpus collosum to the left hemisphere where most individuals hold the language processing areas.

The "Voice Meter Pro" app for the iPad, iPhone and iPod touch, is a simple, but effective app that helps children with autism spectrum disorders (ASD's), voice disorders, or any other child (or adult) monitor the volume of their own voice in a Fun and Engaging way. Children with Asperger’s and other ASD’s often have difficulties producing the appropriate voice volume in different settings. Some children on the autism spectrum speak too quietly. Others speak too loudly. Still others do not compensate adequately for the social milieu or ambient noise level. Understanding abstract concepts, such as the volume of one’s voice, can be difficult for children with ASD's. It’s well understood that adding a visual component to the otherwise abstract concept can often be very helpful for individuals with ASD. OK so how does the app work? Well….if a child is talking to quietly a blue background with a cartoon character struggling to hear is displayed. If a child is talking too loudly the background changes to red and the character puts it’s fingers in its ears. If the volume level is acceptable a green background with a smiling happy character is displayed. • The on screen “volume thermometer” dynamically displays the volume level as it changes. • There’s a "Sensitivity" slider so the adult can adjust the volume sensitivity to suit both the user and the environment. • There’s also a "Dampening" slider. This helps avoid the meter bouncing around in between words by introducing a slight delay before any movement is shown on the “volume" thermometer. • To give the user total control over the app the Upper and Lower limits of the "Green" (acceptable volume area) can now be adjusted by the user. • For convenience the app works in both portrait and landscape modes on all the iPhone, iPod Touch and iPad. • the iPhone version of the app has a switch to enable the iPhone to vibrate should the upper threshold level be exceeded for longer than 4 seconds. We want to make this app the very best it can be and to this end we have included a feedback form inside the app for users to submit any issues or suggestions as to how it can be improved. Why not download the app and give it a try?...... you might find it a very useful tool.
