Custom Acoustic Enclosures for Industrial Noise Control: Yuefa Acoustic Project Case Study

Project Overview

A photovoltaic manufacturer headquartered in Foshan, China, required an effective industrial noise control solution for its production facility in Europe. After evaluating equipment noise at the company's Foshan facility, Yuefa Acoustic developed custom acoustic enclosures tailored to the project's operational requirements.

Project Details

• Client Industry: Photovoltaic Manufacturing

• Project Location: Italy, Europe (destination to be confirmed)

• Project Period: November 2025 – February 2026

• Application: Industrial production line noise control

• Solution: Custom acoustic enclosures for three priority noise areas

• Key Requirements: Noise reduction, equipment accessibility, production line integration, and reliable acoustic performance

When Production Noise Becomes a Workplace Challenge

Noise from the production line at the Hungarian facility had generated complaints from employees working in nearby offices. Local authorities subsequently requested noise control measures, making it important for the manufacturer to address the issue while maintaining normal production operations.

The initial objective was to control noise levels in the workshop offices to 45 dB(A) or lower.

Because the production equipment was similar to that used at the manufacturer's Foshan facility, Yuefa Acoustic conducted an assessment of representative noise sources, including material handling systems, stamping equipment, motors, cutting machinery, and packaging equipment.

Through online meetings, Yuefa Acoustic and the client reviewed the proposed noise control solutions and discussed potential adjustments to the enclosure layout. The client's management team also visited Yuefa's showroom, laboratory, and manufacturing facilities to gain a better understanding of the proposed designs, production capabilities, and relevant project experience.

Following these discussions and a review of project costs, both teams focused on three priority noise areas. The revised acceptance target was set at 70 dB(A) or lower, measured 1 meter from the acoustic enclosures.

This revised target provided a more specific basis for enclosure design, manufacturing, and acceptance testing.

Custom Acoustic Enclosure Design for Production Line Requirements

Once the revised noise control objectives had been established, Yuefa Acoustic optimized the acoustic enclosure design to accommodate the production line layout, equipment dimensions, and operational requirements.

The design improvements included several key measures:

1. Optimized Enclosure Structure and Panel Thickness

The enclosure structure and panel thickness were adjusted to meet the project's acoustic and installation requirements. Composite damping panels were incorporated to improve sound insulation by helping reduce vibration transmission and sound radiation from the enclosed equipment.

2. Improved Sealing for Noise Leakage Control

Gaps around panel joints, access openings, and acoustic doors can significantly affect the overall sound insulation performance of an enclosure.

To address these potential weak points, Yuefa strengthened the sealing design around joints and doors to help minimize sound leakage and improve the effectiveness of the complete enclosure system.

3. Integration with Existing Production Equipment

Industrial acoustic enclosures must do more than reduce noise. They also need to accommodate equipment operation, routine inspection, and maintenance.

The design process therefore considered equipment positioning, installation dimensions, access requirements, and maintenance clearances. These factors helped ensure that the enclosures could be integrated into the existing production line without unnecessarily interfering with daily operations.

This project demonstrates the importance of selecting a custom acoustic enclosure manufacturer with the ability to coordinate acoustic design, structural engineering, and practical manufacturing requirements.

Acoustic Enclosure Testing and Acceptance

With a tight delivery schedule, Yuefa Acoustic coordinated design, procurement, and manufacturing activities to keep the project on track. The acoustic enclosures were assembled at Yuefa's Foshan facility for preliminary testing.

During the initial acceptance test, background noise from equipment operating in adjacent processing areas affected the measurement results. Some of these machines could not be switched off independently, making it difficult to evaluate the enclosures under the intended test conditions.

To address this issue, the team clarified the test requirements, including a background noise limit of 60 dB(A) from surrounding sound sources.

Following the necessary testing arrangements, the enclosures underwent third-party acceptance testing and met the agreed noise control requirements.

This process highlighted an important consideration in industrial noise control projects: reliable acoustic testing depends not only on the enclosure itself but also on background noise, measurement distance, equipment operating conditions, and a clearly defined acceptance procedure.

From Acoustic Design to Manufacturing and Delivery

By February 2026, the custom acoustic enclosures had been manufactured, assembled, and tested at Yuefa's Foshan facility in accordance with the agreed project requirements.

After acceptance, the enclosures were dismantled, packaged, and shipped to the client's European production facility in Italy.

From the initial equipment noise assessment to acoustic engineering, manufacturing, testing, and delivery, the project required close coordination across multiple teams.

Yuefa Acoustic provided a customized industrial noise control solution designed around the client's equipment, production layout, and agreed acoustic performance targets. The project also strengthened Yuefa's experience in coordinating international industrial acoustic projects.

Why Custom Acoustic Enclosures Matter for Industrial Noise Control

For manufacturers operating stamping machines, motors, cutting equipment, material handling systems, and other noisy machinery, uncontrolled equipment noise can affect workplace comfort and create operational challenges.

A properly designed industrial acoustic enclosure can help address these issues by combining sound-insulating structures, vibration damping, effective sealing, and practical access for maintenance.

When evaluating an acoustic enclosure supplier, industrial buyers should consider:

• Noise control targets: Define the required sound pressure level, measurement distance, operating conditions, and acceptance criteria.

• Enclosure construction: Review panel thickness, composite materials, structural rigidity, and sealing details.

• Equipment compatibility: Confirm dimensions, access doors, maintenance clearances, and integration with the existing production line.

• Ventilation and heat management: Ensure that airflow and cooling requirements are addressed without compromising acoustic performance.

• Testing and documentation: Establish background noise conditions, measurement procedures, and third-party testing requirements before production.

The most suitable solution is not necessarily the enclosure with the greatest thickness or highest material specification. It is the solution that meets the project's noise control objectives while remaining practical to install, operate, and maintain.

Yuefa Acoustic: Custom Acoustic Solutions for Industrial and Commercial Applications

Yuefa Acoustic develops acoustic solutions for projects with different sound control requirements, from architectural acoustic materials to specialized acoustic enclosures and soundproof pod products.

For industrial projects, custom acoustic enclosures can help isolate noisy machinery and reduce sound transmission into surrounding work areas. For offices and commercial interiors, soundproof office pods, acoustic pods, and office phone booths provide dedicated spaces for private conversations, focused work, and online meetings.

Although industrial acoustic enclosures and office soundproof pods serve different purposes, both require careful consideration of acoustic performance, structural design, ventilation, sealing, and real-world operating conditions.

As an experienced acoustic product manufacturer, Yuefa Acoustic works with customers to evaluate application requirements and develop solutions suited to their projects.
