Your environmental noise survey company is most likely well-versed in the specifications of sound level meters. But if you're new to the industry or looking to expand, shopping around for these meters can get a bit overwhelming.

Sound level meter measuring is most commonly done in factories, neighborhoods, industrial complexes and airports. Other possible locations include construction sites and auditoriums; think about new applications and locations if you're looking for new customers.

Before you bid on projects, make sure you have the proper audio level meters.

1. Look for an economically priced audio level meter if your company is just starting out or is on a strict budget. These meters may not have the range of more costly ones, but they may suit your needs.

2. Buy high-quality indoor level meters if the majority of your customers create decibel levels low on the spectrum. The majority of these meters test up to 130 dB.

3. Shop for weatherproof outdoor sound level meters if you have any projects that involve leaving your equipment outside. The weather can ruin your electronics if you don't protect them properly.

Action Steps
The best contacts and resources to help you get it done

Use low-cost sound level meter testers

If you're buying in bulk or in need of inexpensive meters, consider exchanging range for cost. You'll sacrifice just a bit of range, in most cases, but if you don't need a meter with these capabilities, a lower-cost tester is right for you.

I recommend: Find economically priced meters from Reliability Direct. Or check out the digital sound meters available at Bosworth Instrument Supply.

Give each employee a useful level meter tester for indoor needs

High-quality sound level meters will have a few extra bells and whistles when compared with more economical testers. Weigh the pros and cons of each before picking a model to buy.

I recommend: Try out sound meters with all the extras at Transcat. If you need to track your readings, a data-logging meter from Zefon International should suit your needs.

Take it to the field with outdoor level meter test equipment

Electronics are not typically known for withstanding harsh weather conditions. Rain, snow, wind and dirt can ruin your meters if you have to leave them outside for an extended period of time for testing purposes. You can buy a kit to add on to your existing meter or you can buy new gear designed to withstand harsh environments.

I recommend: For extended periods of testing in harsh weather conditions, the heavy-duty noise level meter from NoiseMeters has a one-week battery, while the lightweight model can stay out overnight. See if the outdoor gear at Brüel & Kjær will work with the meter you already have.
