Electrophysiology

1. Auditory Brainstem Response (ABR)

An Advanced Electrophysiological Assessment Mapping Neural Activity From The Auditory Nerve Up To The Brainstem. It Provides Critical, Objective Diagnostic Data For Newborn Infant Screenings, Pediatric Threshold Estimations, And Retrocochlear Pathway Evaluations.

  • Completely Objective — Requires No Active Voluntary Response Or Speech Feedback From The Patient.
  • Highly Comfortable — Safely Performed While Infants Or Children Are Naturally Sleeping Or Relaxed.
  • Newborn Gold-Standard — The Premier Screening Method For Early Detection Of Pediatric Auditory Deficits.
  • Retrocochlear Diagnosis — Assists In Localizing Auditory Pathway Lesions And Acoustic Neuroma Symptoms.
  • Auditory Neuropathy Detection — Crucial For Identifying Neural Synchrony Issues In Complex Cases.
Evaluates Wave I Through Wave V Electrical Potential Latencies Along VIIIth Cranial Nerve.

Objective Thresholds

2. Auditory Steady-State Response (ASSR)

An Objective Electrophysiological Threshold Evaluation That Utilizes Frequency-Specific Continuous Stimuli To Reconstruct Detailed Audiograms. By Analyzing Phase-Locked Neural Responses, ASSR Bridges The Gap When Behavioral Testing Is Impossible.

  • Frequency-Specific Audiograms — Reconstructs Detailed Thresholds For 500 Hz, 1000 Hz, 2000 Hz, And 4000 Hz.
  • Severe-To-Profound Loss Evaluation — Uniquely Suited To Differentiate Severe From Profound Hearing Loss.
  • Dual-Ear Simultaneous Testing — Tests Multiple Frequencies In Both Ears Simultaneously For Faster, Precise Diagnostic Acquisition.
  • Air & Bone Conduction Support — Captures Objective Values For Both Conduction Types To Determine Hearing Loss Classification.
  • Direct Amplification Mapping — Provides The Exact Numerical Values Needed To Program Digital Hearing Aids And Cochlear Implants.
Essential For Precise Hearing Aid Fitting & Pediatric Amplification Programming.

Cochlear Localization

3. Recruitment Tests (ABLB & SISI)

Specialized Behavioral Tests Designed To Evaluate Loudness Growth Abnormal Patterns, Helping Clinicians Localize Auditory Path Damage. By Comparing Auditory Sensitivity, These Tests Differentiate Between Sensory (Cochlear) And Neural (Cranial Nerve) Lesions.

  • ABLB Loudness Balancing — Compares Loudness Growth Between A Normal And Impaired Ear To Isolate Recruitment.
  • SISI Increment Sensitivity — Checks The Patient’S Ability To Detect Tiny 1 DB Amplitude Increments At High Levels.
  • Site-Of-Lesion Localization — Clearly Distinguishes Cochlear Sensory Issues From Retrocochlear/Neural Pathology.
  • Meniere’S Disease Screening — Assists In Diagnostic Tracking Of Endolymphatic Hydrops And Related Disorders.
  • Differential Diagnostic Integrity — Provides Crucial Qualitative Verification Alongside Pure-Tone Averages.
ABLB (Alternate Binaural Loudness Balance) & SISI (Short Increment Sensitivity Index) Yield Definitive Cochlear Differential Data.

Speech Recognition

4. Speech Reception Threshold (SRT)

A Standardized Audiometric Assessment Measuring The Lowest Decibel Level At Which A Patient Can Successfully Repeat 50% Of Spoken Spondaic Words. SRT Serves As A Vital Cross-Check For Overall Test Reliability And Real-World Hearing Clarity.

  • PTA Cross-Check Verification — Validates Pure-Tone Average Reliability, Ensuring Accuracy Within ±5 DB.
  • Spondaic Word Comprehension — Uses Phonetically Balanced Two-Syllable Words (Spondees) To Determine Recognition Thresholds.
  • Social Communication Assessment — Measures The Patient’S Functional Auditory Reception In Everyday Conversation Levels.
  • Cochlear Function Validity — Helps Identify Potential Developmental Speech Delay Risks In Children.
  • Rehabilitation Outcome Guidance — Serves As A Baseline To Predict Future Performance With Amplification Systems.
Validates Pure Tone Average (PTA) Within ±5 DB For Clinical Consistency.

Specialized Tests FAQ

Understand How Electrophysiological And Specialized Tests Deliver Objective Results.

Since Infants Cannot Raise Their Hands Or Respond When They Hear A Sound, ABR Allows Us To Objectively Measure Their Auditory System’S Response. Electrodes Placed On The Baby’S Head Measure The Nerve’S Electrical Signals, Verifying Hearing Health While They Sleep.

Recruitment Is A Condition Where Sounds Become Loud Very Quickly As Volume Increases. For Example, A Soft Sound May Be Inaudible, But A Moderately Loud Sound Feels Piercingly Loud. Recruitment Testing (ABLB) Helps Determine If This Cochlear Pathway Issue Is Present.

Most Electrophysiological Assessments (ABR / ASSR) Take Approximately 45 To 60 Minutes, Which Includes Skin Preparation And Electrode Setup. Behavioral Recruitment (ABLB/SISI) And Speech Threshold Testing (SRT) Take 20 To 30 Minutes.

Yes, Completely Safe And Painless. The Tests Use Soft Surface Sensors Applied With Skin-Friendly Gel. There Are No Electrical Shocks Or Uncomfortable Sensations—The Sensors Simply Measure Tiny Electrical Signals Naturally Generated By The Hearing Nerve.
