Acoustical Engineering & Audiology

We provide defensible acoustical and hearing-science analysis for litigation, product liability, and industrial exposure cases. If the question is “what did it sound like, how loud was it, and did it meet the standard?”—we answer it with measurements, models, and math that stand up in court.

Expert Witness • Formidable Partners

Acoustical Engineering & Audiology Expert Witness

Nationally recognized auditory scientist and acoustical engineer with deep expertise in noise exposure, hearing protection, electroacoustics, and standards compliance. Led an ISO/IEC 17025–aligned acoustical testing laboratory for a global hearing-protection brand and contributed to ANSI S12 (Noise) standards, including S12.6 and S12.71.

Brings 30+ years across clinical audiology, product R&D, live sound, and industrial hygiene—specializing in exposure reconstruction, hearing protector fit-testing, speech intelligibility, directional microphone and noise-reduction evaluation, and program audits under OSHA/NIOSH/ANSI/ISO. Widely published and frequently invited to present on hearing conservation, music and entertainment exposures, and device performance.

Standards Leadership

Contributor to ANSI S12 noise standards with ISO/IEC 17025 laboratory leadership and deep familiarity with OSHA, NIOSH, EPA, and ISO compliance requirements.

Exposure Reconstruction

Recreates historical noise environments using calibrated measurements, modeling, and dose analytics for defensible litigation findings.

Hearing Protection Expertise

Fit-testing and performance evaluation of earplugs, earmuffs, and electronic protectors under ANSI S12.6/S12.71, ISO 4869, and MSHA/OSHA programs.

Published Authority

Widely published and frequently invited to present on hearing conservation, entertainment exposures, electroacoustic performance, and program audits.

Technical Expertise. Our acoustical engineering team combines doctoral-level training in audiology and hearing science with decades spent in electroacoustics, hearing conservation, and product testing. Experience includes leadership of ISO/IEC 17025 acoustical laboratories, participation in ANSI S12 development, and publications in journals such as the Journal of the Acoustical Society of America and Journal of Occupational and Environmental Hygiene.

We bring practical experience across clinical diagnostics, industrial acoustics, hearing-aid development, and live sound engineering—enabling precise, real-world assessments that hold up under scrutiny.

What We Do

Comprehensive acoustical engineering and hearing-science support from initial exposure assessments to courtroom-ready findings.

Noise & Exposure Assessment

Occupational and environmental noise surveys, personal dosimetry and in-ear monitoring with time-weighted and peak analyses, standards-based evaluations under OSHA, MSHA, NIOSH, IEC 61672, ANSI S1/S12, ISO 9612, and exposure reconstruction when historical data are incomplete or disputed.

Hearing Protection & Conservation

Fit-testing and attenuation verification for earplugs, earmuffs, and electronic protectors, program audits and compliance reviews, evaluation of labeling and instructions, integration with product acoustics, and failure-mode analysis linking overexposure to preventable hearing loss.

Product & Device Acoustics

Electroacoustic testing and performance characterization for hearing protection devices, hearing aids, consumer audio, toys, alarms, and wearables with standards compliance verification and signal-processing feature evaluations.

Building & Environmental Acoustics

Community noise investigations, room and space acoustics analysis, reverberation and STIPA evaluations, and mitigation design with modeled performance predictions.

Entertainment & Event Safety

Assessments of live sound reinforcement practices, in-ear monitoring systems, on-stage exposure, hearing conservation program adequacy, and compliance under OSHA, ANSI, and industry best practices.

Speech Intelligibility & Audibility

Emergency alarm audibility and speech-in-noise performance evaluations, reverberation impacts in architectural and occupational contexts, and audibility assessments for code compliance.

Methods & Tooling

Class-1 instrumentation, proven test paradigms, and transparent analytics ensure every opinion is reproducible and standards-driven.

Instrumentation

Class-1 sound level meters and dosimeters (IEC 61672), acoustic calibrators (IEC 60942), impulse and binaural recorders, and head-and-torso fixtures deployed when required.

Test Paradigms

Real-ear/MIRE measurements, fit-testing per ANSI S12.6/S12.71, STIPA intelligibility assessments, directional and noise-reduction evaluations, and reverberation decay metrics.

Data Science

Time-history analytics, FFT and 1/3-octave processing, Monte Carlo uncertainty estimates, and transparent workflows that withstand Daubert and Frye scrutiny.

Quality Control

ISO-style documentation, calibration traceability, and full chain-of-custody retention to document every measurement, model, and conclusion.

Our Analytical Process

Structured engagements deliver defensible results through disciplined intake, measurement, modeling, and communication.

Intake & Issue Identification

Define claims, regulatory context, and decision criteria so opinions are Daubert/Frye ready from the first conversation.

Data Collection

Gather policies, exposure data, calibration logs, product specifications, training records, and medical or audiologic evidence.

Measurement & Validation

Conduct field and laboratory measurements with Class-1 instrumentation, including personal dosimetry, octave and 1/3-octave analysis, impulse logging, and binaural recordings.

Modeling & Reconstruction

Develop propagation, reflection, and exposure models to simulate historical or disputed acoustic environments.

Compliance Assessment

Apply the correct OSHA, NIOSH, ANSI, ISO, or EPA rules for the relevant timeframe—never retrofitting modern requirements onto past conditions.

Findings & Mitigation

Quantify exposure, evaluate protection adequacy, and recommend realistic engineering or administrative controls.

Reporting & Testimony

Deliver clear, technically sound, and fully reproducible findings suitable for expert reports, mediation, deposition, and trial testimony.

Deliverables You Can Use

Clear work products translate complex acoustical evidence into findings, visuals, and action plans that withstand scrutiny.
