Two sentences are played into the ears at the same time. The child has to repeat back both words heard.Ĭompeting Sentence Test (Binaural Separation) Two words are played into the ears at the same time. The Staggered Spondee Word (SSW) test is a dichotic listening test used in the evaluation of auditory perceptual abilities in children. The child has to repeat back all 4 digits heard. In this test 2 digits are played simultaneously into each ear. The student may have to ignore speech from one source (chatter between the students) while focusing on the teacher’s voice. This is called binaural separation and it is vital to everyday listening, particularly in a classroom. In some situations, the student will have to ignore the signal being delivered to one ear while focusing on the signal being presented to the other ear. An example scenario is a lively debate where speech is coming from different sides and will be overlapping. The auditory system has to process different signals in each ear at the same time and merge them – a process called auditory integration. If the topic of discussion is familiar to the child then they may use their existing knowledge to help fill in the gaps, however if there is no pre-existing knowledge then the child may quickly lose the thread of what is being taught which may impact their learning.ĭichotic listening refers to auditory stimuli that are presented to both ears at the same time but when the stimulus being presented to each ear is different. A student with poor auditory closure will not fill in these gaps and may struggle to make sense of what is being taught. Also, if a student is sitting at a table with a fidgety student, then the sounds from fidgeting may partially mask or obscure what the teacher is saying.Ī student with good auditory closure will be able to fill in the missing or masked parts of the speech and follow what the teacher is saying. For example, the sound of air conditioning or children playing outside may be present while the teacher is speaking. Almost all listening occurs with some level of background noise. An inability to use this information has been found to be a leading cause of difficulty understanding speech in noisy environments, such as the classroom.Īuditory closure plays an important role in everyday listening because it relates to our ability to fill in missing or distorted portions of the auditory signal so that the whole message can be correctly interpreted. Importantly, it measures the ability of children to use the spatial cues that help differentiate a person speaking from distracting speech sounds.

LiSN-S is an adaptive, virtual reality speech test that measures speech perception ability in noisy environments. As a result, they may miss instructions or information. If a student has been looking down to take notes, they may take some time to find and focus on the teacher’s voice again. Binaural interaction allows us to:Ĭhildren with poor binaural interaction will struggle to pick out a teacher’s voice from the other sounds in the classroom and to track the teacher’s voice as it moves around.

PLEASE NOTE THAT BEFORE CARRYING OUT AN APD DIAGNOSTIC ASSESSMENT YOU WILL NEED TO FIRST ATTEND FOR A FULL DIAGNOSTIC HEARING ASSESSMENT TO RULE OUT HEARING LOSS AND OTHER CAUSES OF LISTENING DIFFICULTIES. Once diagnosed, APD can be managed through auditory training, remote microphone systems, classroom accommodations, additional support, and other strategies. The NHS estimates that as many as one in 20 children may have some degree of auditory processing difficulty. Difficulty understanding accents and cannot follow fast speech.Difficulty concentrating unless it is very quiet in the room.Mishears or misunderstands what is being said.APD can affect a child’s ability to learn, follow directions, read, engage in conversation, and reach their full potential. This is referred to as auditory processing difficulties/disorder (APD). AUDITORY PROCESSING DISORDER (APD)Įven when a child has normal hearing, they may still face challenges with listening and processing information. PLEASE NOTE THAT BEFORE CARRYING OUT AN AUDITORY PROCESSING DISORDER ASSESSMENT YOU WILL NEED TO FIRST ATTEND FOR A FULL DIAGNOSTIC HEARING ASSESSMENT TO RULE OUT HEARING LOSS AND OTHER CAUSES OF LISTENING DIFFICULTIES.
