简短回答

A credible noise-control case study should show the noisy source, baseline condition, treatment scope, receiver point, measurement method, result, site limitations, and enough photos or drawings to understand the context.

What a useful case should include

Case studies are most useful when they show the problem, source, site layout, treatment type, openings, access requirements, and before-and-after evidence.

Noise source, equipment model or process type, and operating condition.
Baseline noise, target point, receiver distance, and project goal.
Solution scope: enclosure, doors, louvers, silencers, panels, barriers, or room treatment.

Read dB results carefully

A result value should state where and how it was measured. If the source, load, distance, or background noise changed, the case should explain that change.

Photos need context

Photos help prove that a project exists, but they do not prove performance by themselves. The best cases connect photos with layout, source location, receiver point, and treatment boundary.

How to use cases in your RFQ

Use case studies to describe the type of problem you have, then send your own equipment data, site photos, target receiver point, and documentation requirements for project review.

选型要点

Use this checklist when comparing supplier case studies or preparing future HEMU case pages.

Do not treat another project result as your project guarantee.

Ask whether before-and-after values use the same source condition and receiver point.

Separate real project evidence from stock photos, generic renderings, and product-only images.

2	Target receiver point, distance, current level, target level, and local limit if any.
3	Proposed treatment type, openings, doors, ventilation, silencers, and service access.
4	Measurement method, report requirement, before-and-after expectation, and acceptance party.
5	Photos, drawings, installation constraints, destination country, and timeline.

买家常见问题

Can a supplier case study prove my project result?

No. It can show similar experience, but your result depends on your source, layout, openings, and measurement point.

What should I look for in a dB case result?

Look for source condition, receiver point, distance, operating mode, method, background noise, and whether the before-and-after conditions match.

Can HEMU publish project cases without test data?

Project pages can describe scope and application only if evidence exists. Exact performance claims need owned measurements or customer-approved reports.

Prepare a clearer acoustic enclosure RFQ

Send drawings, site photos, noise targets, access requirements, and airflow constraints for engineering review.
