Know More About Triplett Sound Level Meter
What is Sound Level Meter?
A sound level meter, commonly referred to as a sound meter or decibel meter, is an instrument utilized to measure and evaluate the intensity or volume of sound within a given environment. It serves as a valuable tool for assessing noise levels and ensuring adherence to regulatory standards or guidelines.
Sound Level Alert displays sound level readings on an extra large LCD ideal for viewing from a distance. Sound level is displayed in db (decibels) and also represented by bright, color-coded status LEDs. The user can program a sound level limit that when exceeded will change the LEDs from green to ﬂashing red and display an ‘OVER’ message.
How are Sound Level Alerts used?
The Sound Level Alert can be placed in auditoriums, hospital wards, class rooms, and other school areas. When the noise level reaches a predetermined alarm level, the alert LEDs will warn the occupants. The relay output permits the user to connect an external audio or visual device for more dramatic, customized alerts.
What is a Sound Level Datalogger?
A sound level datalogger meter measures, displays, and stores sound level measurement data over an extended period of time. Up to 20,000 readings can be stored in the meter, each with the date and time stamp. Readings can be recalled on the meter’s display or they can by downloaded to a PC. Included software permits the user to view, graph, print, and export data to a spreadsheet. This allows detailed analysis, trend identification, and compliance monitoring.
How Does a Voice Meter Work
Noise level meter is a device that measures the intensity of the sound. It is used by people who work in places where noise control is a requirement. Have you ever had a problem with the noise level in your home or your place of work? Are you looking for an effective way to get rid of this problem? If yes, then this sound measuring device can provide you with a solution to these problems.
The voice meters works by picking up vibrations from sound and converts them into electrical signals. The speed of electrical pulses vary according to loudness of the sound. In other words, the higher the volume of sound, the larger number of pulses per second. A dial then converts these electrical signals into decibels, and acoustic measurement values are shown on the display of the sound meter.
What is the Range of Sound Level Meter?
Sound dB meter can measure the decibel level in any environment and help you to make the proper adjustments to control the sound. However, to get the right measurements from sound level meter, it is very important that you know the ideal range of sound meter. To be more specific, sound decibel meter generally measures over a range of about 30 to 130 dB.
What is an Acceptable dB Noise Level?
The term dB noise level is a measurement of the intensity of a sound, in terms of decibels. It is often used when determining whether a sound is too loud to cause hearing loss. The maximum acceptable dB noise level is usually determined by an employer or other person in authority who determine the policies for the workplace.
A noise level of 60 dB is widely accepted as the maximum background sound produced in a business environment. In general, it is recommended that the average noise level in an office should be around 50 dB.
Sound levels of 70 dB or less are generally considered safe. Any sound that is at or above 85 dBA has a higher chance of damaging your hearing over time.
How accurate are sound level meters?
Sound and noise level meters are highly accurate devices specifically made to measure the intensity of sound or noise in a given environment. The accuracy of sound level meters can vary based on several factors, including calibration, quality of the device, and adherence to industry standards. Being said this, high-quality sound level meters we offer at Triplett are known to provide accurate readings ranging from ±1.5dB, ±3.5dB@1kHz accuracy. However, keep in mind that the accuracy also depend on several other external factors like humidity, temperature, and background noise. To ensure the highest level of accuracy every time, ensure to calibrate sound level meters according to the set guidelines.
Which are the application areas of sound level meters?
Sound level meters find endless applications across industries. A few of the industries that get benefitted from the use of these versatile instrument include:
- Occupational safety and health: The meters are largely chosen to ensure workplace safety and health assessments. They are utilized to monitor and analyze noise levels in construction sites, factories, and other industrial settings to guarantee compliance with noise regulations.
- Entertainment industry: Noise level meters are one of the commonly used tools in the entertainment industry, such as music concerts, theaters, and film production. They are effective in monitoring sound levels in live performances, thus protect performers and audience members from excessive noise exposure.
- Research and Development: They are utilized in development activities and scientific research to analyze the effects of noise on wildlife, human health, and natural habitats. Sound and noise level meters are also used for studying various acoustic phenomena, including the behavior of sound in different mediums, and sound propagation, among others.
- Building Acoustics: Noise level meters find immense applications in building acoustics. The meters are chosen to measure and assess the acoustic properties of rooms, auditoriums, concert halls, and other spaces. The instruments also offer valuable data for deciding on soundproofing measures and optimizing the acoustic quality in architectural and interior design projects.
- Product Testing: In the automotive and consumer electronics industries, rigorous product testing and evaluation is imperative. This is where the role of sound level meters comes in. They are opted to check the noise levels produced by different products, including vehicles, appliances, and electronic devices. The use of these meters helps to ensure compliance with noise standards.
- Environmental Noise Monitoring: They are used to monitor/assess environmental noise pollution, measure noise levels in residential areas, near airports, highways, among others. Thus, these instruments contribute to evaluating the impact on communities and enforcing noise control regulations.
Why calibrate a sound level meter?
Calibrating a sound level meter regularly is highly recommended to ensure accurate and reliable measurements of sound and noise levels. Keep in mind that, over time, the meter's sensitivity can drift, resulting in incorrect readings. By choosing to calibrating the meter, you can verify its accuracy and adjust it if necessary. This process involves comparing the measurements of the meter to a reference standard with a known accuracy.
Follwing are the steps to follow when calibrating the meter:
- Set the sound level meter to the appropriate calibration mode or adjustment setting.
- Adjust the calibration level on the sound level meter. Refer to the user manual for detailed instructions on how to adjust the calibration level.
- Activate the sound source used for calibration.
- Position the sound source at the specified distance from the sound level meter.
- Compare the reading on the sound level meter with the known value of the calibration sound source.
- Adjust the calibration level on the sound level meter if there is a significant difference.
- Repeat the calibration process if necessary.
- Now, ensure to check and recalibrate the sound level meter periodically according to the recommended schedule or guidelines.
