Acoustic Startle Reflex Tinnitus Detection Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting and measuring tinnitus are inadequate as they rely on subjective responses from humans and animals, leading to inaccuracies and difficulties in diagnosing and quantifying the condition, especially in cases where communication is challenging or malingering occurs.
Innovation Solution
The use of acoustic startle reflex analysis to objectively measure tinnitus by quantifying the subject's startle response to various sound patterns, including gap inhibition and pre-pulse inhibition, allowing for the detection and severity assessment of tinnitus without relying on subjective feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If subjective response methods are used to detect tinnitus, then the testing process is simple and easy to administer, but the measurement precision and reliability are insufficient due to malingering and communication challenges
Solution Approach 1:
The patent replaces subjective psychological reporting with objective physiological measurement by substituting the mechanical/behavioral response system with a physiological detection system that measures acoustic startle reflex and gap detection thresholds, eliminating malingering concerns while maintaining ease of administration
Solution Approach 2:
The patent introduces an intermediary physiological measurement system (acoustic startle reflex measurement) that mediates between the tinnitus condition and the detection process, providing objective data that bridges the gap between subjective experience and measurable evidence
2Reliability
If behavioral training methods are used in animal models, then tinnitus can be detected through learned responses, but the device complexity and training time requirements increase significantly
Solution Approach 1:
The patent extracts the core physiological response (acoustic startle reflex) from the complex behavioral training protocol, isolating the fundamental reflex that can be measured without requiring extensive training, thereby simplifying the overall testing procedure while maintaining reliability
Solution Approach 2:
The patent performs preliminary action by measuring baseline acoustic startle reflex characteristics before tinnitus induction, establishing a reference point that simplifies subsequent detection and eliminates the need for complex post-training comparisons
3Measurement precision
If complex behavioral manipulations are applied to animal models, then the detection sensitivity may improve, but the loss of time for training and the difficulty of implementation increase
Solution Approach 1:
The patent applies self-service by utilizing the animal's natural, innate acoustic startle reflex without requiring external training or manipulation, allowing the physiological system to provide the measurement data automatically through its inherent response properties

Data Source
AI summary
Objectively measuring tinnitus in human and animal subjects. A subject is exposed to an alteration in a sound pattern otherwise qualitatively similar to the subject's tinnitus and a startle reflex is induced. The subject's acoustic startle response is obtained and used to determine whether the subject detected the alteration of the sound pattern.
