Fluke 945 Sound Meter

The Fluke 945 Sound Meter is a Class 2 precision sound level meter designed for accurate acoustic measurements in industrial, environmental, and occupational health settings. Professionals including acoustic engineers, occupational safety specialists, and environmental consultants rely on this instrument to measure sound pressure levels ranging from 30 dB to 130 dB with exceptional accuracy and repeatability. This meter solves the critical challenge of identifying noise hazards in workplaces, monitoring compliance with noise regulations, and assessing hearing protection effectiveness in real-world environments.

Product Overview

The Fluke 945 Sound Meter operates on the fundamental principle of converting acoustic pressure waves into electrical signals through a precision microphone capsule, which are then amplified and processed by advanced digital circuitry to display sound pressure levels in decibels (dB). The instrument features a Class 2 certified measurement capability with a frequency-weighted A-scale response that mimics human hearing sensitivity, making it ideal for occupational noise exposure assessments and environmental noise monitoring. The dual-display design provides simultaneous readings of sound pressure level and peak hold values, enabling technicians to capture both steady-state and transient noise events without missing critical data points.

What distinguishes the Fluke 945 from standard sound level meters is its integration of advanced signal processing algorithms that minimize measurement errors from wind noise and electromagnetic interference, combined with a rugged polycarbonate housing that withstands harsh industrial environments. The instrument incorporates automatic level ranging across its measurement span, eliminating the need for manual range switching and reducing operator error. Its fast and slow response time settings (per IEC 61672 standards) allow professionals to capture both rapid impulse noise and steady ambient sound, making it exceptionally versatile for comprehensive acoustic site surveys and noise impact assessments.

Key Features

• Class 2 Certified Accuracy: Meets IEC 61672-1 standards with ±1.4 dB accuracy at 94 dB reference calibration point, ensuring reliable measurements for regulatory compliance and occupational safety assessments
• Dual-Display Peak Hold Function: Simultaneously captures and displays both real-time sound pressure levels and peak values, preventing loss of transient noise events during industrial machinery operation or impact noise assessment
• Automatic Level Ranging: Eliminates manual range switching with intelligent auto-ranging circuitry that optimizes display resolution across the entire 30-130 dB measurement span
• Fast and Slow Response Settings: Switchable response times (125 ms fast / 1 second slow) allow measurement of both impulse noise and steady-state sound in compliance with international acoustic standards
• Integrated Microphone with Windscreen: Pre-calibrated precision microphone with supplied foam windscreen reduces wind-induced measurement errors in outdoor environmental monitoring applications
• Compact Rugged Design: Impact-resistant polycarbonate housing with ergonomic grip withstands daily use in construction sites, manufacturing facilities, and field survey environments

Applications and Use Cases

• Occupational Noise Exposure Assessment: Measure employee exposure to noise hazards in manufacturing plants, construction sites, and airports to ensure compliance with OSHA noise exposure limits and implement appropriate hearing conservation programs
• Environmental Noise Monitoring: Conduct community noise impact studies around highways, railway lines, and industrial facilities to assess environmental compliance with local noise ordinances and regulatory thresholds
• Hearing Protection Device Evaluation: Verify the effectiveness of earplugs and earmuffs by measuring sound attenuation in real-world workplace conditions before and after personal protective equipment installation
• HVAC and Equipment Commissioning: Assess noise levels from heating, ventilation, and air conditioning systems during installation and maintenance to ensure compliance with building specifications and occupant comfort standards
• Acoustic Testing and Troubleshooting: Identify noise sources in mechanical systems, identify bearing failures, and detect abnormal vibration-induced noise in rotating equipment for preventive maintenance programs

How to Use

Begin by installing four AA batteries into the battery compartment on the rear panel and verify the low battery indicator is not illuminated on the LCD display. Attach the supplied foam windscreen to the microphone inlet to minimize wind noise during outdoor measurements. Press the power button to activate the meter and allow 30 seconds for the internal circuitry to stabilize before taking measurements. Position the microphone at the measurement location, maintaining the instrument vertically with the microphone facing the sound source at approximately 45 degrees to avoid reflections from your body.

Select the appropriate response time setting based on your measurement objective: use Fast (F) response for transient or impulse noise like impact sounds, and Slow (S) response for steady ambient noise measurements. Activate Peak Hold mode if you need to capture maximum sound levels during intermittent noise events. Allow the display to stabilize for 3-5 seconds before recording readings. For regulatory compliance documentation, record multiple measurements at different locations and times, noting environmental conditions such as temperature, humidity, and background activity. After completing measurements, switch off the power and store the meter in a protective case to preserve the microphone calibration.

Frequently Asked Questions

What is the difference between Class 1 and Class 2 sound level meters?

Class 1 meters have measurement accuracy of ±1.1 dB and are used for precision laboratory and reference measurements requiring the highest accuracy standards. Class 2 meters like the Fluke 945 have ±1.4 dB accuracy and are designed for field surveys, occupational noise assessments, and general-purpose sound measurement where slightly lower precision is acceptable but ruggedness and portability are essential. For most industrial and environmental applications, Class 2 accuracy exceeds regulatory requirements while offering superior durability.

How often should the Fluke 945 be calibrated?

The Fluke 945 should be acoustically calibrated annually using a Fluke 820-2 Sound Level Calibrator to maintain Class 2 certification and ensure measurement accuracy within specification. If the meter is used in demanding industrial environments or dropped, calibration should be performed more frequently. We recommend sending the meter to an authorized Fluke service center in India for professional calibration with traceable certification documentation for regulatory compliance records.

Can the Fluke 945 measure impulse noise and impact sounds accurately?

Yes, the Fluke 945 is specifically designed to measure impulse noise through its Fast response time setting (125 millisecond integration time) and Peak Hold function that captures the maximum sound pressure level during transient events. This makes it suitable for assessing impact noise from pneumatic tools, metal stamping, and machinery startup sounds. For extremely rapid impulses below 125 milliseconds, specialized impulse sound level meters with even faster response times may be required, but the 945 covers the vast majority of occupational and environmental noise assessment scenarios.
