Sound Level Meter & Noise Monitor Suppliers in Sydney

Class 1 and Class 2 are two types of sound level meters that measure sound levels in decibels (dB). Class 1 sound level meters are more accurate and have a wider frequency range than Class 2 sound level meters. Class 1 meters are suitable for measuring noise levels in industrial environments, for occupational health and safety, and for compliance with noise regulations. Class 2 meters are less accurate but more affordable and are suitable for measuring noise levels in general environments, such as for traffic noise, construction sites, and residential areas. Both types of meters use microphones to convert sound waves into electrical signals and display the results on a digital screen.

A sound level meter typically has a measurement range of 30 to 130 decibels (dB). The range of a sound level meter is important because it determines the minimum and maximum sound levels that the meter can measure accurately. It is also important to note that different sound level meters may have different frequency weighting and time weighting settings that affect the accuracy of their measurements.

This involves testing and adjusting the meter's sensitivity to sound waves at specific frequencies. Calibration should be done periodically, ideally every year or more often if the meter is used frequently or in harsh conditions. Some sound level meters may have a self-calibration feature, but it is still recommended to have a professional calibration done for the most accurate results.

The weight and size of a sound level meter can vary depending on the specific model and brand. Typically, a sound level meter may weigh between 100-200 grams and have dimensions of around 10cm x 5cm x 2cm. They can easily fit in a pocket or small carrying case, making them convenient to use on-the-go. Some models may be larger and heavier, but these are usually designed for more advanced or specialized use cases.

It depends on the specific sound level meter being purchased. Some models may come with a carrying case or protective cover, while others may not. It is important to check the product details or contact the manufacturer to confirm if a carrying case or protective cover is included. If not, it may be recommended to purchase one separately to protect the sound level meter during transportation and storage.

Some sound level meters may use rechargeable batteries, while others may use replaceable batteries. The battery life of a sound level meter can range from a few hours to several days, depending on the usage and battery capacity. It is recommended to check the manufacturer's specifications for the specific sound level meter to determine the battery life.

Common measurement modes include A-weighted, C-weighted, and Z-weighted, as well as peak, fast, and slow response times. Some sound level meters may also have octave band analysis capabilities. The number and types of measurement modes available on a sound level meter will vary depending on its intended use and level of sophistication.

Yes, many sound level meters are compatible with computer software for data analysis. The software allows for the collection and analysis of data from the sound level meter, making it easier to identify trends and patterns in noise levels. Some popular software options include SoundView, NoiseTools, and Cirrus Research's dBAir. The compatibility of the sound level meter with specific software may vary, so it is important to check the manufacturer's specifications before purchasing.

It is advisable to check the product's user manual or contact customer support to know more about the warranty period. Generally, most sound level meters come with a one-year warranty period that covers any manufacturing defects or malfunctions. It is always recommended to choose a reputable brand and read the warranty terms and conditions carefully before purchasing a sound level meter.

A sound level meter (SLM) is a device used to measure the sound pressure level (SPL) in decibels (dB) of a sound source.

• Frequency is a measure of the pitch of the sound, and SLMs can measure the frequency of a sound source. This is useful when evaluating the noise from different sources with different frequencies, such as low-frequency noise from industrial equipment or high-frequency noise from electronic devices.
• Time-weighting is a measure of how the SLM responds to changes in the sound level over time. There are three different time-weighting modes: Fast, Slow, and Impulse. Fast mode is used to measure sudden changes in the sound level, Slow mode is used to measure continuous noise, and Impulse mode is used to measure short-duration noise events.
• Octave bands are a way to divide the frequency range of a sound into different bands, each with a different center frequency. SLMs can measure the sound level in each octave band, which is useful for evaluating the frequency content of the sound and identifying the most significant sources of noise.

In conclusion, modern SLMs can measure other parameters besides sound level, such as frequency, time-weighting, and octave bands. These additional parameters provide more information about the sound source and help identify the most significant sources of noise.
