SHS 250 Speech & Hearing Sciences Final Exam 2026/2027 -
Questions and Answers 100% Verified Complete Verified
Answers - Pass Guaranteed - A+ Graded
SHS 250 Final Exam assesses integrated knowledge of speech and hearing sciences, including acoustic phonetics,
speech production/perception, language development, hearing science, audiology principles, disorders,
assessment, and evidence-based practice. The exam emphasizes conceptual reasoning and clinical application at
a rigorous undergraduate level. It contains 50 multiple-choice questions, each with four distractors and a fully
worked rationale that explains why the keyed answer is correct. Questions are organized into clearly labelled
sections that mirror the major content areas of the course. Targeted learning outcomes include: Analyze speech
acoustics and perceptual cues using source-filter theory and psychoacoustic principles.; Apply anatomical and
physiological mechanisms of speech and hearing to clinical scenarios.; Interpret audiological and speech
assessment data to inform evidence-based intervention planning.. Every item has been reviewed for clinical
accuracy, current guidelines, and clarity so that students can study with confidence and self-correct as they work
through the bank. Use it as a high-yield review immediately before the exam, or as a structured practice tool
during the unit - the rationales double as concise teaching notes. The recommended writing time is 3 hours, with a
passing score of 75% (A+ 97%). Aligned with Aligned with ASHA 2026 Certification Standards, CAA 2026
Standards, and current evidence-based practice guidelines; suitable for US university upper-division final
examinations. standards and reflects the question style commonly seen on accredited program examinations.
Section 1: General (Questions 1-50)
1 Which acoustic cue primarily distinguishes /b/ from /p/ in English?
A) Voice onset time (VOT)
B) Formant transition direction
C) Fundamental frequency (F0)
D) Nasal murmur duration
Answer: A
Rationale: VOT differentiates voiced and voiceless stops: /b/ typically has short-lag
VOT while /p/ has long-lag VOT in English. Formant transitions, F0, and nasal
murmur do not reliably distinguish this voicing contrast.
2 During vowel production, which structure primarily determines formant
frequencies?
A) Vocal fold vibration rate
B) Shape and length of the vocal tract
C) Subglottal pressure magnitude
D) Velopharyngeal port closure timing
Answer: B
Rationale: According to source-filter theory, the vocal tract acts as a filter; its shape
and length determine formant frequencies. Vocal fold vibration rate sets F0,
,subglottal pressure affects intensity, and velopharyngeal closure affects nasality, not
formants.
3 Which auditory structure performs the initial mechanical frequency analysis of
sound?
A) Tympanic membrane
B) Ossicular chain
C) Basilar membrane
D) Auditory nerve
Answer: C
Rationale: The basilar membrane's stiffness gradient creates a tonotopic place code,
performing mechanical frequency analysis. The tympanic membrane and ossicles
transmit sound, and the auditory nerve encodes neural signals.
4 Which phenomenon best explains improved speech understanding in noise when
binaural cues are available?
A) Binaural squelch
B) Temporal integration
C) Upward spread of masking
D) Loudness recruitment
Answer: A
Rationale: Binaural squelch uses interaural timing and level differences to suppress
noise and enhance speech. Temporal integration, upward spread of masking, and
loudness recruitment do not explain binaural advantage.
5 A child says 'tar' for 'car'. Which phonological process is evident?
A) Fronting
B) Stopping
C) Gliding
D) Final consonant deletion
Answer: A
Rationale: Fronting replaces velar sounds with alveolar sounds, as in 'car' !’ 'tar'.
Stopping, gliding, and final consonant deletion do not describe this substitution
pattern.
6 Which pure-tone audiogram configuration suggests noise-induced hearing loss?
A) Flat 40 dB HL across frequencies
B) Rising from 40 dB at 250 Hz to 10 dB at 8000 Hz
, C) Notched at 3000-6000 Hz with recovery at 8000 Hz
D) Air-bone gap at 500-2000 Hz
Answer: C
Rationale: Noise-induced hearing loss classically shows a 3000–6000 Hz notch with
recovery at 8000 Hz. Flat loss, rising loss, and air-bone gaps suggest other
etiologies.
7 Which research design best establishes causality in speech-language intervention?
A) Randomized controlled trial
B) Case series
C) Cross-sectional survey
D) Single-subject AB design
Answer: A
Rationale: Randomized controlled trials minimize bias and support causal inference.
Case series, surveys, and single-subject designs provide weaker evidence for
causality.
8 Which muscle abducts the vocal folds during respiration?
A) Thyroarytenoid
B) Posterior cricoarytenoid
C) Lateral cricoarytenoid
D) Cricothyroid
Answer: B
Rationale: The posterior cricoarytenoid is the sole abductor of the vocal folds.
Thyroarytenoid, lateral cricoarytenoid, and cricothyroid serve adduction, adduction,
and pitch elevation respectively.
9 Which ICF framework component addresses communication participation
restrictions?
A) Body functions
B) Body structures
C) Activities and participation
D) Environmental factors
Answer: C
Rationale: The ICF's activities and participation domain captures communication
participation restrictions. Body functions/structures and environmental factors are
separate components.
