Sound Level Meter Price in Bangladesh 2026

Sound level meter price in Bangladesh starts at ৳39,500 for the Lutron SL-4033SD with SD card data logging, alongside the compact Hioki FT3432 for quick, everyday noise checks. ASTZ stocks both models, covering everything from instant on-the-spot readings to continuous long-term noise monitoring.

Choosing between these two comes down to one question: do you need to log data over time, or just check a noise level right now? That distinction shapes which unit actually fits your work, and it’s worth sorting out before you order.

What is a Sound Level Meter? (Overview)

A sound level meter measures sound pressure levels in decibels, giving an objective, repeatable reading of how loud an environment is. It’s built to respond to sound roughly the way the human ear does, making its readings meaningful for both safety compliance and general noise assessment.

How a Sound Level Meter Measures Decibels (dB)

The device picks up sound through a built-in microphone, converts the sound pressure into an electrical signal, and processes it into a decibel reading shown on the display. Higher readings mean louder sound pressure at the microphone’s location.

dBA vs dBC Weighting — What It Means for Your Reading

dBA weighting filters the reading to match how the human ear perceives loudness, making it the standard for workplace noise compliance. dBC weighting is flatter across frequencies and better suited to measuring low-frequency sound, such as machinery rumble or bass-heavy audio testing.

Types of Sound Level Meters We Offer

Hioki FT3432 — Compact Sound Level Meter

The FT3432 is a compact, straightforward unit for quick noise checks — point it, read the display, done. It suits situations where you need a fast reading without logging data over time.

Lutron SL-4033SD — Sound Level Meter with SD Card Data Logging

The SL-4033SD adds SD card data logging to standard sound level measurement, letting you record noise levels continuously over hours or days for compliance documentation or trend analysis. Price: ৳39,500.

Basic vs Data-Logging Sound Level Meter — Which One Do You Need?

If you only need to confirm a noise level in the moment, the FT3432 does the job without extra complexity. If you need a documented record over time — for a compliance report or a noise study — the SL-4033SD’s data logging is the reason to pay more.

Applications of Sound Level Meter

Workplace Noise Monitoring & OSHA-Style Compliance

Safety officers measure noise levels in factories and workshops to confirm they stay within safe exposure limits, protecting workers from long-term hearing damage.

Construction & Industrial Site Noise Assessment

Site managers check noise from heavy equipment and machinery to manage worker exposure and stay within local noise regulations.

Classroom, Office & Hospital Indoor Noise Monitoring

Institutions monitor ambient noise in learning and healthcare environments where excessive sound disrupts concentration, communication, or patient recovery.

Traffic & Environmental Noise Surveys

Researchers and municipal teams measure road, rail, and general environmental noise to assess community impact and support planning decisions.

Audio System & Speaker Sound Testing

Audio technicians use sound level meters to verify speaker output matches specifications and confirm sound systems perform within a safe, intended range.

Automotive & Engine Noise Measurement

Automotive engineers measure engine and exhaust noise during testing to confirm vehicles meet interior comfort standards and local noise regulations.

Who Needs a Sound Level Meter in Bangladesh

Safety & Industrial Hygiene Officers

Anyone responsible for workplace safety compliance needs documented noise readings to identify and address hazardous exposure levels.

Factory & Construction Site Managers

Site managers use regular noise checks to manage worker safety and respond to complaints or regulatory requirements.

Acoustic Consultants & Audio Engineers

Professionals assessing room acoustics or audio equipment performance rely on accurate, calibrated dB readings for their evaluations.

Researchers & Environmental Compliance Teams

Teams studying environmental or occupational noise exposure need reliable instruments capable of both instant and logged measurements.

Why Choose ASTZ for Sound Level Meter in Bangladesh

Genuine Hioki & Lutron Instruments

Both brands are established names in test and measurement equipment, and every unit we sell is genuine, not a rebranded clone.

Accurate, Reliable Readings for Compliance Work

When a reading needs to hold up for a safety report or regulatory check, the accuracy of Hioki and Lutron instruments gives you confidence in the numbers.

Warranty, Support & Nationwide Delivery

Every purchase includes manufacturer warranty and support from our team, with delivery available across Bangladesh.

How to Choose the Right Sound Level Meter

Do You Need Data Logging or Just Instant Readings?

This is the main decision point — occasional spot checks don’t need logging capability, while ongoing monitoring or compliance documentation does.

Measurement Range Requirements (dB Range)

Confirm the dB range fits your environment; industrial and construction noise typically requires a wider measurement range than office or classroom monitoring.

Portability vs Long-Term Monitoring Setup

A compact handheld unit like the FT3432 suits quick fieldwork, while the SL-4033SD’s data logging is better suited to a fixed monitoring setup over extended periods.

Frequently Asked Questions

What is the price of a sound level meter in Bangladesh?

The Lutron SL-4033SD data-logging model costs ৳39,500 at ASTZ; contact us for current pricing on the compact Hioki FT3432.

How does a sound level meter work?

It captures sound through a built-in microphone, converts the sound pressure into an electrical signal, and displays the result as a decibel reading.

What is the difference between dBA and dBC?

dBA weighting matches how the human ear perceives loudness and is standard for workplace compliance, while dBC weighting better captures low-frequency sound like machinery rumble.

Why is a data logging sound level meter needed?

Data logging lets you record noise levels continuously over time, which is necessary for compliance documentation, trend analysis, or long-term environmental studies rather than a single spot reading.

What is a safe noise level in a factory or office?

Workplace noise exposure limits vary by regulation and exposure duration, but sustained levels above roughly 85 dBA over a full workday are generally considered a hearing-risk threshold requiring protective measures.

What are the benefits of buying from ASTZ?

Genuine Hioki and Lutron instruments, reliable accuracy for compliance work, manufacturer warranty, and delivery across Bangladesh.
