The only specialist military NIHL audiological service built entirely around the diagnostic framework endorsed by the High Court in Abbott v MoD [2026] EWHC 941 (KB). CPR Part 35 compliant reports. rM-NIHL methodology. Individual case-specific clinical judgment. Serving defendant solicitors and the Ministry of 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.
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.
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.
Beyond military NIHL, this practice provides comprehensive medico-legal audiological services for solicitors, insurers, and claims handlers across the full spectrum of hearing loss litigation — including industrial NIHL, acoustic shock, occupational noise exposure, and hearing loss following accidents or medical procedures.
All reports meet CPR Part 35 requirements and are structured for direct use by legal teams without further clinical interpretation.
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.
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).
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).
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.
Middle ear function assessed bilaterally. Conductive pathology excluded before sensorineural attribution. Acoustic reflex thresholds documented.
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.
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.
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] 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.
Adil Patel is a HCPC-registered audiologist specialising in medico-legal audiological assessment and military noise-induced hearing loss litigation. With four years of clinical and medico-legal experience, he has conducted audiological assessments across a wide range of NIHL and personal injury cases and has direct, operational experience within the MoD NIHL litigation framework.
He holds a BSc (Hons) in Audiology and is registered with the Health and Care Professions Council. All reports are personally prepared, personally signed, and personally defended.
Adil's methodology is fully aligned with Abbott v MoD [2026] EWHC 941 (KB) and applies the rM-NIHL diagnostic framework of Moore, Lowe and Cox (2022) as endorsed by Mr Justice Garnham. He is available for expert witness attendance in contested cases and for CPR 35.6 reply reports throughout England, Wales, and Scotland.
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.
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.
