About the Practice

Built Specifically for the Defence.

Crown Audiological Services Ltd is a specialist medico-legal audiology practice established to serve defendant solicitors, insurers, and the Ministry of Defence in noise-induced hearing loss litigation.

Following the landmark judgment in Abbott v MoD [2026] EWHC 941 (KB), the High Court settled the diagnostic framework for military NIHL cases — endorsing the rM-NIHL methodology of Moore, Lowe and Cox (2022) and requiring individual, case-specific clinical judgment rather than mechanistic application of industrial guidelines. Every assessment and report produced by this practice is built around that framework from the ground up.

Adil Patel BSc Hons Audiology has operated within the MoD NIHL litigation framework, developing direct, first-hand knowledge of precisely where audiological evidence is vulnerable to challenge — and how to produce defence-side evidence that withstands it. That operational insight, combined with rigorous clinical methodology, is the foundation of everything this practice does.

This practice does not serve the claimant side. It exists to serve the defence — with the standards, precision, and independence that MoD litigation demands.

Services

Two Specialist Service Streams

Every service is available individually or as part of a volume instruction programme. All reports are CPR Part 35 compliant and delivered to a 10 working day turnaround unless otherwise agreed.

Primary Service

Military Noise-Induced Hearing Loss

Specialist defence-side assessments for MoD litigation — built around Abbott v MoD [2026]

The definitive diagnostic framework for military NIHL is now settled. This service delivers every element the court requires: rM-NIHL diagnosis, individual AAHL percentile assessment using in-service audiogram series, ISO 7029:2017 corrections, de minimis quantification, and tinnitus causation analysis — all in a single CPR Part 35 compliant report.

This is not an adapted industrial NIHL service. It is built exclusively for military cases, exclusively for the defence.

  • Full ISO 8253-1 audiometric assessment — air and bone conduction, all frequencies 0.25–8 kHz
  • rM-NIHL diagnosis per Moore, Lowe & Cox (2022) — Abbott [2026] endorsed standard

  • Industrial NIHL assessment — CLB/LCB methodology for non-military cases
  • Acoustic shock and sudden hearing loss assessment
  • Hearing loss following road traffic accidents and head trauma
  • Tinnitus assessment and quantification — THI, VAS, audiometric correlation
  • Hearing aid needs assessment and lifetime cost projection

A Note on Independence

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. This practice does not operate on a volume-processing model. Every case receives individual attention, individual clinical judgment, and individual expert sign-off.

Clinical Methodology

Every Assessment. The Same Standard. Every Time.

The following methodology is applied to every military NIHL instruction. It is not adapted from an industrial protocol. It was designed specifically for military cases and aligns precisely with the framework endorsed by Mr Justice Garnham in Abbott v MoD [2026] EWHC 941 (KB).

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, as required by Abbott [2026] §8(a).

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) with the modifications required by Abbott [2026]: individual AAHL percentile applied (not automatic 50th percentile), ISO 7029:2017 norms with 2.4dB baseline correction, 6 kHz TDH39 artefact assessed case by case. Service-attributable loss separated from presbycusis. De minimis threshold quantified against 4dB binaural average. 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 deployed as contemporaneous defence evidence where relevant. Report delivered within 10 working days of assessment.

Why Individual Percentile Assessment Matters

Abbott [2026] §8(a) expressly requires that experts do not apply the 50th percentile AAHL automatically. Instead, the claimant's position in the population must be established from their available military audiogram series. A claimant whose in-service audiograms show consistently better-than-average hearing cannot be assessed as though they had average hearing — doing so inflates the attributed NIHL. This practice applies individual percentile assessment on every instruction. Many volume providers do not.

Abbott v MoD [2026] Alignment

Built Around the Judgment. Not Retrofitted to It.

Abbott v MoD [2026] EWHC 941 (KB) established the definitive framework for military NIHL diagnosis, quantification, and damages. Every service offered by this practice was designed around that framework. The following table maps each of the nine generic findings from the judgment to the corresponding practice standard applied on every instruction.

Court Finding (Abbott [2026])
This Practice's Standard
FINDING 7CLB/LCB inapplicable for military cases
rM-NIHL applied exclusively for all military instructions. CLB never used for 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 report and deployed proactively as defence evidence.
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 rejected
rM-NIHL (2022 revision) exclusively. No AI models. No M-NIHL 2020 or earlier versions.

What Makes This Practice Different.

Built Around Abbott [2026] — Not Retrofitted to It

This practice was established after the Abbott judgment. Its methodology was designed around the court's findings from the outset. Every structural element — individual percentile assessment, military audiogram series analysis, de minimis quantification, Woodrup v Nicol hearing aid analysis — reflects what the court required.

Inside Knowledge the Claimant Side Cannot Match

Adil Patel has direct, first-hand experience within the existing MoD NIHL litigation framework. That experience provides precise knowledge of where claimant-side audiological evidence is clinically vulnerable — where the rM-NIHL has not been applied correctly, where individual percentile assessment has been substituted with automatic 50th percentile, where NOHL screening has been omitted. That knowledge is available exclusively to the defence.

Transparent, Verifiable, 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. There are no opaque panel arrangements and no undisclosed subcontracting.

The pilot programme offer: 50 cases over 90 days, independently audited, with a no-obligation evaluation report at completion.
