Project RFQ Support

Engineering Silence.
Start with a clearer RFQ.

Shanghai HEMU Acoustics Technology Co., Ltd. is a professional provider of acoustic insulation and noise control solutions. As industrial noise-control requirements rise, R&D testing environments become more demanding, and offices shift toward flexible quiet spaces, we help industrial, utility, automotive, electronics, home appliance, university laboratory, and modern workplace clients reduce noise interference, improve acoustic testing precision, and meet international environmental and safety standards.

We support RFQ preparation across industrial acoustic enclosures, office pods, anechoic and semi-anechoic test rooms, soundproof test chambers, and custom acoustic components by organizing equipment dimensions, noise targets, airflow paths, service access, installation limits, and document requirements.

Compliance documents, acoustic test reports, material files, certificates, and acceptance records should be confirmed by product configuration, destination market, and the approved technical proposal rather than assumed from a generic catalog claim.

We prioritize eco-conscious acoustic materials and recyclable metal structures, and promote energy-saving soundproof design to reduce operating energy use and material waste. Our acoustic solutions are designed for European and North American acoustic testing, environmental, and safety expectations.

The Meaning of Hemu

Growth above. Roots below.

Hemu (禾木) is a Chinese name carrying simple and beautiful meaning.

"He" (禾) symbolizes growth, order, and harvest. "Mu" (木) symbolizes roots, structure, and support. Together, they describe how we approach acoustic engineering: clear, stable, and worthy of long-term trust.

HE

Growth with order

Careful cultivation, steady rhythm, and measurable progress.

MU

Structure with roots

A solid foundation that keeps complex engineering work stable.

PROMISE

Reliable, clear, stable

A long-term partner for acoustic environments that must perform.

How We Plan Projects

Start from the noise source, receiver point, airflow, openings, and document needs so purchasing, engineering, and acceptance discussions stay aligned.

01
Noise source check

Start with the equipment, room, generator, booth, or chamber need, then define the receiver point and operating condition.

02
Project scope

Compare whether the buyer needs a machine enclosure, generator enclosure, room-level treatment, pod, or test chamber path.

Anechoic test chamber technical cross-section
03
Openings and airflow

Plan ventilation, exhaust, doors, panels, cable entries, ducts, and service access before the quotation scope is finalized.

04
Document scope

List the drawings, test method, certificates, material files, and acceptance records that must be confirmed for the destination market.

05
Configuration confirmation

Align panel construction, finish, packing, delivery, installation support, and acceptance expectations in the approved proposal.

Semi-anechoic chamber for measurement projects
06
Traceable follow-up

Keep project files, spare-part notes, and acceptance requirements tied to the final configuration for later service discussion.

Core Capabilities

Industrial noise control, office privacy, acoustic testing, and custom components — from design to lifecycle service.

Factory-built or site-built

Industrial Acoustic Enclosures

Custom acoustic enclosures and rooms for machinery, compressors, fans, pumps, generators, and production equipment — engineered around noise targets, airflow, service access, heat release, cable routing, and site boundary requirements.

Precision measurement rooms

Anechoic Chambers

Anechoic, semi-anechoic, RF/EMC, and acoustic test chamber options for acoustic measurement, sensor calibration, and product noise testing. Background noise, cut-off frequency, room geometry, and acceptance method should be confirmed by project.

Quiet workspace modules

Office Pods & Booths

Office phone booths, meeting pods, privacy booths, and focus work pods for open-plan offices, airports, lobbies, and flexible workplaces — creating private call and concentration spaces with minimal disruption to existing layouts.

Serviceable acoustic systems

Soundproof Chambers & Lifecycle Support

Soundproof test chambers for rapid noise screening and product functional testing on production lines or in laboratories. Custom acoustic doors, absorber-barrier modules, spare-part notes, and service records keep projects traceable and maintainable.

Documents & Acceptance Confirmation

A clearer document framework for project approval and acceptance.

Certificate, material, performance, and quality-management information is confirmed by project type and destination market so purchasing, engineering, EHS, and lab teams can evaluate requirements quickly.

The final document package is confirmed by product configuration, application, and import or site-acceptance requirements.
