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 this test 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 this test 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 this test 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.

QuickSIN©

The QuickSIN© is a speech in noise recording. It consists of sentences recorded in four-talker noise. There are twelve sets of sentences with six sentences in each set. Each set includes one sentence at each of the following signal-to-noise ratios: 25, 20, 15, 10, 5, and 0 dB. Every sentence has five key words that are scored as correct or incorrect. The lists are equivalent and provide a quick and accurate assessment of hearing aid performance. Each listening condition takes approximately two minutes to administer. The QuickSIN© is modification of the SIN and, as the title suggests, is a shorter version of the SIN. It is appropriate for most adults. See BKB-SIN for a similar test for children.

The QuickSIN© includes a) auditory test recording, and b) manual and score forms. The extensive manual contains information on administration, scoring, and interpretation. Normative data for adults is included.

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.

The male talker reads “Dissertation on a Roast Pig” by Charles Lamb in a monotone voice, and a female reads from “On Walden Pond” by Henry David Thoreau in a monotone voice. Both the male and female talker speak for approximately six minutes each for a total of twelve minutes of recorded voice.

Connected Discourse© consists of the audio recording only. This product does not include administration instructions or normative data. It is assumed that purchasers of Auditec’s products are well trained in their use, purpose, and interpretation.

Speech In Noise©

The Speech in Noise© (SIN)¹ test was developed to help determine how much a given hearing aid or pair of hearing aids helps an individual understand speech in a background of noise, compared to listening unaided or with other hearing aids. The test consists of a series of female-talker recordings of the IEEE (modified Harvard) sentences as the target speech, and four-talker babble (three women and one man) as the noise source. Five sentences are recorded at each of four signal-to-noise (S/N) ratios: 15 dB, 10 dB, 5 dB and 0 dB S/N, all at the 0 dB VU meter calibration level, followed by a similar series recorded at a signal level 30 dB lower than the calibration level (-30 dB re 0 VU).

Therefore, there are 20 sentences at each level for a total of 40 sentences (or 4 IEEE lists), all of which constitutes a block. There are nine blocks of the SIN test, so that nine comparisons can be made without repeating sentences. Each listening condition takes approximately twelve minutes to administer.

The Speech in Noise© includes a) audio recording, and b) instructions and score forms as printable pdf files. The instructions provide information on administration.

Hearing Loss Simulation©

The Hearing Loss Simulation© attempts to demonstrate what a hearing loss might sound like to the hearing impaired. It is in two main parts; part one demonstrates a flat “conductive” loss down to 40 dB in 10 dB steps (40 dB of attenuation), and part two simulates high frequency losses. The latter section employs both male and female talkers in quiet and in noise. 25 The Hearing Loss Simulation demonstration consists of sharp (48 dB/oct) low-pass filters at 2000, 1000 and 500 Hz, illustrating precipitous high frequency losses. Brief introductions precede each section.

The Hearing Loss Simulation© includes a) audio recording, and b) instructions. The three-page instructions include representative audiograms. Normative data is not included for this product because it is not for measuring. It is only used for demonstration. Available from Auditec, Inc. Use the “Buy Now” button below or call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order. FREE shipping to contiguous US.
