LNT/MLNT

The Lexical Neighborhood/Multisyllabic Lexical Neighborhood Tests (LNT-MLNT) were developed primarily for use with cochlear implant children.  Determining the benefits of sensory aids (i.e. hearing aids or cochlear implants) is essential for the proper management of hearing impaired children.  Open-set word recognition tests have provided important diagnostic information relative to the benefits of sensory aids.  The information garnered from these tests indicates the extent of neural representation of words in a child’s long-term lexical memory.

The most used open-set word recognition test for children has been the PBK-50 lists.  However, it has been noted that for hearing-impaired children the PBK-50 does not assess the abilities of these children validly.  The LNT-MLNT has been shown to be a more sensitive measure of spoken word recognition in these children.

The LNT-MLNT was developed along theoretically motivated current models of spoken word recognition in listeners with hearing impairment.   The development of the LNT-MLNT was based on the assumptions of the Neighborhood Activation Model (NAM), which proposes that words are organized into “similarity neighborhoods” based on their frequency of occurrence in the language and the number of phonemically similar words, or neighbors, within the lexical neighborhood.  A dense lexical neighborhood contains many phonemically similar words, whereas a sparse lexical neighborhood has few phonemically similar words.  Words that occur often and come from sparse lexical neighborhoods are easier for children to identify than words with the opposite lexical characteristics.

The stimulus words for the LNT-MLNT were selected according to two criteria: 1. The words had to be familiar to young children with limited vocabularies. 2. The selection was based on current models (NAM) of word recognition and lexical access.  Stimuli on the LNT-MLNT are separated into easy and hard word lists.

The LNT/MLNT includes a) audio recording, and b) manual and score forms as printable pdf files. The nineteen-page manual includes administration information and normative data for children. Available from Auditec, Inc. Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order.

BKB-SIN

The BKB-SIN test is a speech in noise test for children. It was developed for children (ages 5 and up), cochlear implant patients, and adults for whom the QuickSIN test is too difficult. Other uses include: demonstrating the benefits of amplification, predicting performance with hearing aids in loud, noisy environments, assessing directional microphone performance, estimating children’s performance for soft speech, and screening for auditory processing disorders in children.

The BKB-SIN uses 18 equivalent list pairs for estimating SNR loss. It features Bramford-Kowal-Bench sentences in four talker babble, uses easier sentences than the QuickSIN, and has norms for children, adults, and cochlear implant users. CD 1 (Standard BKB-SIN) has the target talker and background babble recorded on the same channel of the CD, at pre-recorded signal-to-noise ratios.  CD 2 (Split Track BKB-SIN) has the target talker and background babble recorded on separate channels of the CD.

The BKB-SIN includes a) audio recording (CD1 and CD2), and b) manual and score forms. The 27-page manual is comprised of administration, interpretation, and development. Normative data for ages 5 and up is included. Available from Auditec, Inc. Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order.

Minimal Auditory Capabilities (MAC)

The Minimal Auditory Capabilities (MAC) battery is specifically targeted to the cochlear implant patient. It consists of a series of tasks which are graded in difficulty. This is a standardized test. Most of the MAC battery sub-tests assume that a patient’s hearing loss has occurred post-lingual, but it can be employed as a means of evaluating the hearing abilities of persons for whom traditional speech materials are too difficult.

The MAC Battery consists of the following subtests: 1) Question/ Statement, 2) Vowels, 3) Spondee Recognition, 4) Noise/ Voice, 5) Accent, 6) CID Everyday Sentences, 7) Initial Consonants, 8) Spondee Same/ Different, 9) SPIN High-Context Sentences, 10) Familiar Sounds, 11) Monosyllabic Words (NU-6, List 1B), 12) Four-Choice Spondee, 13) Final Consonants

The Minimal Auditory Capabilities (MAC) battery includes: a) audio recording, and b) manual and score forms as printable pdf files. This thirteen-page manual contains development, administration, and interpretation information. Normative data is included for adults. It can be assumed children over the age of 11 would score as well (or nearly as well) as adults. Available from Auditec, Inc. Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order.
