Longitudinal Outcomes of Children with Hearing Impairment


Hi, I’m LOCHI the lion from the Longitudinal Outcomes of Children with Hearing Impairment study.

This study is conducted by the National Acoustic Laboratories (NAL) to examine the long-term speech, language, psychosocial and

New clinical tools availalve (PEACH+ and TEACH+)

The PEACH+ and TEACH+, like the PEACH and TEACH, is used to evaluate the effectiveness of the child’s use of hearing in real-world environments. Additionally, it provides an estimate on the child’s ease of listening in different situations. Ratings will be used to build a picture of the child’s functional performance and listening efforts in real life.

We've made these forms electronically fillable to make it easier for parents, clinicians and researchers to use.

Click on the following test names to access the PEACH+ or the SELF+ fillable forms.

Alternatively, click here to access the new PEACH rating scale which includes a graph to compare the child's performance to normal hearing children.

Normative data sub-study

In addition to testing our LOCHI kids, we’ve also been testing children of similar ages with normal hearing. At the moment, we are aiming to recruit normal hearing 9 year olds. Our aim is to use the results from these assessments to compare the performance of children with hearing loss to that of children without hearing loss. Read more…
