Audiology booths: up to 62 dB(A) attenuation for reliable diagnostics

In healthcare establishments, the quality of the acoustic environment directly conditions the reliability of medical examinations. Audiometric tests require a controlled level of silence and effective acoustic insulation to avoid any noise disturbance likely to alter the results.

In a hospital environment, silence is not a comfort: it’s a functional requirement. The reliability of an audiometric test depends directly on the level of ambient background noise. Any uncontrolled noise pollution compromises the reproducibility of measurements and, ultimately, the quality of diagnosis. Groupe Boët responded to this challenge at the Complexe Hospitalo-Universitaire International Mohammed VI in Rabat with high-performance industrial acoustic solutions.

Acoustic requirements in hospitals

The Mohammed VI University Hospital in Rabat is an international reference facility, with specialized ENT and hearing aid departments. This type of structure combines particularly severe acoustic constraints: continuous intense activity, a complex technical environment, and medical requirements subject to strict international standards.

In this context, noise control is not a peripheral option. It conditions the conformity of examination protocols, and directly engages the establishment’s medical responsibility. Noise management must therefore be part of a rigorous engineering approach, integrating operating constraints right from the design stage.

Background noise and reliability of ENT examinations

Audiometric tests are based on the detection of very low-intensity sound signals. Any residual noise in the measurement space – whether airborne, structural or related to technical equipment – directly disturbs the accuracy of the detected hearing threshold. An uncontrolled acoustic environment generates erratic results, inaccurate diagnoses and non-reproducible protocols.

Groupe Boët was therefore faced with a specific challenge: to design and install Audiology booths capable of guaranteeing extremely low background noise levels, in an active hospital, on a complexly coordinated multi-lot site.

Solution: customized Audiology booths

Following an acoustic design and dimensioning phase, Groupe Boët designed and installed two high-performance Audiology booths, specially developed for this environment. The acoustic equipment deployed achieves acoustic attenuation of up to 62 dB(A), meeting the most demanding standards applicable in medical environments.

Each cabin incorporates an ultra-quiet ventilation system, guaranteeing air renewal without the introduction of parasitic noise. LED lighting has been selected and positioned to match clinical examination conditions. Technical passages – cabling, fluids, connectors – have been treated with particular attention to acoustic tightness, a critical point in maintaining the integrity of overall acoustic protection.

The entire system was commissioned on site by Groupe Boët teams, with electrical and safety compliance validated. Schedule management, in the context of a multi-lot site, required close coordination with the other trades, respecting the deadlines imposed by the service opening schedule.

Commissioning and measurable results

The two Audiology booths are now fully operational and integrated into the CHU Mohammed VI infrastructure. The results are in line with the objectives defined during the design phase. Practitioners benefit from a stabilized measurement environment, enabling reproducible examinations under optimum acoustic conditions. Patients benefit from a quiet environment, conducive to accurate diagnosis.

For the establishment, this installation represents equipment that complies with international medical standards, and is compatible with current accreditation protocols. The acoustic protection provided ensures the continuity and reliability of diagnostic activities over the long term.

Groupe Boët is backed by ISO 9001 and ISO 19443-certified manufacturing, and has mastered the main demanding construction codes: EN 15085, ASME, RCC-M, CODAP and CODETI. This rigorous manufacturing process guarantees long-lasting, compliant and traceable acoustic equipment.

Acoustic expertise for the most demanding environments

This project at the Mohammed VI University Hospital in Rabat illustrates Groupe Boët’s ability to operate in highly constrained environments, combining in-depth industrial acoustic studies, customized design and controlled installation. From sizing to commissioning, each stage is carried out with the same rigorous engineering approach, whatever the sector of activity – medical, industrial, energy or heritage.
