The Expert's Duty to the Court

Every report produced by this practice is the independent professional opinion of Adil Patel BSc (Hons) Audiology, prepared in accordance with CPR Part 35 and the expert's overriding duty to the court (CPR 35.3), which takes precedence over any obligation to the instructing party. The practice accepts instructions from any party in litigation; the expert's opinion is not influenced by who instructs.

Clinical Methodology

A Consistent Clinical Process.

The following methodology is applied to military NIHL instructions and is informed by the diagnostic framework considered by the High Court in Abbott v MoD [2026] EWHC 941 (KB). It is offered as the practice's own clinical approach; instructing solicitors should satisfy themselves of its applicability to the facts of any individual case.

01

Pre-Assessment Case Review

Service records, military audiogram series, noise exposure history, GP records, and AFCS documentation reviewed before the assessment commences. The individual AAHL percentile is established from the in-service audiogram series at this stage, in line with the approach considered in Abbott [2026].

02

ISO 8253-1 Audiometric Assessment

Pure-tone audiometry conducted in a sound-treated environment using calibrated equipment (certificate available on request). Air and bone conduction measured at 0.25, 0.5, 1, 2, 3, 4, 6, and 8 kHz bilaterally. Minimum three threshold measurements per frequency. Test-retest reliability verified within ±5dB at all frequencies.

03

Tympanometry and Acoustic Reflex Testing

Middle ear function assessed bilaterally. Conductive pathology excluded before sensorineural attribution. Acoustic reflex thresholds documented.

04

rM-NIHL Diagnosis and Quantification

Diagnosis applied using rM-NIHL (Moore, Lowe & Cox 2022) informed by the approach considered in Abbott [2026]: individual AAHL percentile applied (rather than an automatic 50th percentile), ISO 7029:2017 norms with 2.4dB baseline correction, 6 kHz TDH39 artefact considered case by case. Service-attributable loss separated from presbycusis. De minimis threshold quantified. Tinnitus onset chronology assessed and cross-referenced with audiometric series.

05

CPR Part 35 Report

Full written report addressed to the court. Verbatim PD35 §3.3 statement of truth. Court duty confirmed. All documents reviewed listed. Military audiogram series considered as contemporaneous evidence where relevant. Report delivered within the timescale agreed at instruction.

Why Individual Percentile Assessment Matters

The Abbott [2026] judgment indicates that the application of an automatic 50th percentile AAHL is not appropriate where contemporaneous in-service audiograms are available. A claimant whose in-service audiograms show consistently better-than-average hearing should not be assessed as though they had average hearing — doing so risks inflating the attributed NIHL. This practice applies individual percentile assessment on every military NIHL instruction.

Abbott v MoD [2026] — Practice Approach

How This Practice Approaches the Judgment.

Abbott v MoD [2026] EWHC 941 (KB) provides important judicial guidance on military NIHL diagnosis, quantification, and damages. The table below sets out, for each generic finding, the corresponding clinical approach taken by this practice. This is the practice's own interpretation of the judgment; instructing solicitors should read it in full and reach their own view.

Generic Finding (Abbott [2026])
This Practice's Approach
FINDING 7CLB/LCB inapplicable for military cases
rM-NIHL applied for military instructions; CLB methodology used only in industrial / non-military cases.
FINDING 8(a)Individual percentile assessment required — not automatic 50th percentile
Military audiogram series reviewed pre-assessment. Individual AAHL percentile established before any correction is applied.
FINDING 8ISO 7029:2017 with 2.4dB baseline correction
ISO 7029:2017 population norms applied with 2.4dB correction as standard.
FINDING 6Military audiograms are reliable contemporaneous evidence
In-service audiogram series analysed in every military NIHL report.
FINDING 4NIHL under 4dB binaural average will usually be de minimis
Explicit de minimis quantification documented in every report.
FINDING 3Tinnitus delay weakens causation — scrutiny increases over time
Onset chronology assessed against audiometric series. Credibility cross-referencing built into report structure.
FINDING 9Hearing aids recoverable only where intention, benefit and proportionality proven
Actual benefit analysis per Woodrup v Nicol. No automatic recommendation based on diagnosis alone.
FINDING 86kHz TDH39 artefact assessed case by case — no automatic deduction
Case-by-case assessment applied. Documented in report where relevant.
FINDING 5AI diagnostic methods and M-NIHL 2020 not preferred on the facts of Abbott
rM-NIHL (2022 revision) applied. AI diagnostic models not used.

Practice Profile

A Specialist Practice. Independently Run.

Post-Abbott Methodology

The practice was established in 2026 with a clinical methodology informed by the Abbott judgment from the outset — individual percentile assessment, military audiogram series analysis, de minimis quantification, and Woodrup v Nicol hearing aid analysis. Each instruction is approached on its own facts.

Independent Expert Opinion

The practice's overriding duty under CPR 35.3 is to the court, not to any instructing party. Reports set out the expert's independent clinical opinion on the basis of the evidence available, identifying both the strengths and limitations of that evidence. The practice has particular experience of defendant-side military NIHL instructions but accepts instructions from any party.

Transparent and Independently Insured

Every credential is publicly verifiable before instruction is placed. HCPC registration is searchable at hcpc-uk.org. Companies House registration is publicly accessible. Professional indemnity insurance certificate is provided on request.
