If you’ve ever stood next to an industrial egg washing machine during a morning operation shift, you’ve probably noticed a low, continuous hum punctuated by soft, rhythmic thuds. For small-scale poultry farmers expanding their production to meet local grocery store demands, or for medium-sized egg processing plants upgrading their equipment, noise level is rarely the first thing listed in product specs—but it’s one of the most important factors for long-term workplace comfort, regulatory compliance, and equipment longevity. As a supplier of industrial egg washing machines, I get asked this question at least three times a week: How loud is it, really? Most manufacturers give vague decibel ranges, and I’ve seen too many customers wind up with machines that disrupt their team’s focus, or even fail local occupational safety rules, because they took a generic range at face value. Today, I’m breaking down the real noise levels of our equipment, why they vary, and what that means for your operation. Egg Washing Machine
First, let’s get the science right. Noise is measured in decibels (dB), a logarithmic scale that means a 10 dB increase is perceived as twice as loud to the human ear. Normal conversation is around 60 dB, a vacuum cleaner is about 70 dB, and a busy street corner hits around 85 dB. OSHA (the U.S. Occupational Safety and Health Administration) sets a limit of 85 dB for an 8-hour workday—any higher, and businesses are required to provide hearing protection for workers, with higher limits for shorter exposure times. This isn’t just a formality: long-term exposure to over 85 dB can cause permanent hearing damage, even if you don’t feel pain in the moment. That’s why noise level isn’t just a comfort issue—it’s a legal one, too.
Now, back to egg washing machines. There’s no one-size-fits-all number here, because the noise depends on three key factors: the machine’s capacity, its design, and how it’s installed. Let’s start with capacity, because that’s the biggest variable. For small-scale machines designed for 500 to 2,000 eggs per hour (ideal for backyard farm co-ops or small local producers), we measure noise at around 72 to 78 dB when tested at a 1-meter distance from the machine’s control panel. For context, that’s about as loud as a moderately busy restaurant or a quiet office printer—loud enough to hold a conversation without shouting, so your team can easily coordinate tasks during a shift without yelling over the machine.
Next, medium-capacity machines, which handle 2,000 to 10,000 eggs per hour, are where the numbers shift. These machines have larger washing chambers, higher-powered water pumps, and more robust conveyor systems to move eggs faster through the wash, rinse, and drying cycles. When tested at 1 meter, these hit between 78 and 84 dB. That’s right around OSHA’s 8-hour limit—so for a team member standing next to the medium machine for the full shift, we strongly recommend providing basic hearing protection like foam earplugs, or adjusting their station to rotate away from the machine every hour. This isn’t a flaw in the machine; it’s a product of the higher throughput. A 10,000-egg-per-hour machine is moving 1.5 tons of eggs an hour, so you’re going to have more mechanical vibration and water flow than a small-scale model designed for occasional use.
Then there are large-scale industrial machines, built for 10,000 to 50,000 eggs per hour (used by large processing plants that ship eggs across state lines or borders). These are the workhorses of the industry, but they’re also the loudest, measuring 82 to 88 dB at 1 meter. Here’s the important caveat: at this level, OSHA requires employers to implement a full hearing conservation program, including annual hearing tests for workers, if exposure is consistent over 8 hours. But even with that, these machines are designed with built-in noise reduction features that many cheaper competitors skip—like insulated metal chassis, rubber vibration dampers under the conveyor, and quiet-running water pumps with variable speed controls. I’ve had customers with large plants tell me they actually compare our large-scale machines to older models that hit 95 dB or more, so ours are significantly quieter without sacrificing speed or cleaning performance.
Now, why do some manufacturers give lower numbers than this? It all comes down to where they take the measurement. A lot of low-quality suppliers will test noise at the machine’s furthest edge, or while the machine is running empty (no eggs going through the line) instead of a full load of eggs. When eggs are moving on the conveyor, they make soft, subtle thuds as they nudge each other into position, and the water spray bounces off their shells, which adds a small amount of noise that isn’t present when the machine is empty. That’s why we always test our machines at full load, 1 meter from the operator’s control panel—where your team will actually be standing while running the machine. It’s a small detail, but it makes a huge difference in what you’ll experience on the floor.
Another common question I get: Do our machines have any extra noise when we switch cycles, like from washing to drying? The short answer is no. Our machines are designed with smooth, gradual cycle transitions, so there’s no sudden spike in noise that would startle workers or make it hard to hear alerts. The drying cycle uses low-pressure, high-velocity air, but the fan is mounted in a sound-dampened compartment, so the noise level stays consistent throughout the entire operation. We also add emergency stop buttons on either end of the machine, and we’ve calibrated the control panel’s alert sounds to be just loud enough to hear over the background noise without being jarring.
Now, let’s talk about installation, because that’s a huge part of the equation that most customers don’t think about. A machine sitting on a concrete floor will have far more vibration noise than one mounted on rubber isolators, which we offer as an optional add-on for all our models. Vibration travels through solid surfaces, so if your machine is placed next to a metal wall or a metal conveyor frame, that can amplify the noise by 3 to 5 dB—enough to push a medium-capacity machine from 80 dB to 83 dB, which crosses into OSHA’s hearing conservation territory. We always send a setup guide with every machine, and our technicians will walk you through proper placement: leaving at least 1 foot of space around the machine for air flow, placing it on a level, non-metallic base, and avoiding mounting it near office areas or break rooms. For customers looking to reduce noise even further, we also offer sound-dampening enclosure kits for all models, which can cut noise by 4 to 6 dB—turning an 82 dB large-scale machine into 76 dB, which is quiet enough for an open-floor plan without hearing protection.
I want to be transparent here: no industrial egg washing machine is going to be as quiet as a residential refrigerator. These machines are designed for high-volume, consistent use, and they have to move thousands of eggs an hour while spraying water and operating motors that generate inherent noise. But the difference between a well-built, quiet machine and a cheap, loud one is night and day for your team. I’ve seen one of our small-scale machines installed at a farm in Ohio where the owner used to run a 1,200-egg-per-hour machine that was so loud, his employees would have to stand 10 feet away to talk during a shift. After switching to our model, the owner told me his team can now hold full conversations while standing right next to the machine, and they no longer complain of headaches at the end of the day. That’s the kind of real-world impact that noise level has, and it’s why we don’t cut corners on insulation or vibration dampening.
We also test every single machine before it leaves our warehouse, not just for cleaning performance, but for noise level. We use a Class 1 sound level meter calibrated to international standards, and we include a test report with every shipment, so you can see exactly what noise level to expect once the machine is installed and running at full capacity. We don’t give generic ranges that include empty-load tests or measurements taken from 3 meters away—our numbers are based on real, on-the-floor conditions, which is what matters most to our customers.
Another thing that sets our machines apart is that noise level doesn’t come at the cost of efficiency. Some suppliers will skimp on motor power to make their machines quieter, which means they take longer to wash eggs or use more water. Our machines use energy-efficient motors with variable speed controls, so you can adjust the water pressure and conveyor speed based on your egg type (large, extra-large, small) without increasing noise level. We’ve tested this: when you lower the conveyor speed to process smaller eggs, the noise drops by 1 to 2 dB, while still maintaining a consistent cleaning performance that meets USDA standards for egg safety. That’s a big deal, because a lot of our customers are shipping eggs that have to meet strict federal regulations, so cleaning performance is non-negotiable—we don’t ask you to choose between safety and comfort.
Let’s also address the elephant in the room: regulatory compliance. For our customers in the U.S., OSHA’s rules are clear, but many of our international customers have their own standards, like the EU’s Noise at Work Directive, which sets an 8-hour limit of 80 dB, with hearing protection required above that. That’s one reason we’ve invested so much in noise reduction: our medium and large-scale models meet both OSHA and EU standards, so you don’t have to worry about failing a workplace inspection. For customers operating on a smaller scale, our 72 to 78 dB models are well below both standards, so they’re ideal for operations where hearing protection isn’t required at all.
I’ve been supplying egg washing machines for over 12 years, and one mistake I see customers make is prioritizing capacity over all other factors, including noise. I had a customer in Texas a few years ago who bought a 50,000-egg-per-hour machine for his new plant, and he didn’t ask about noise level until after it was installed. The machine hit 89 dB, which meant he had to outfit his entire shift with hearing protection, and he had to add a separate sound booth for his quality control team who worked next to the line. By the time he realized the issue, he’d already spent money on installation and modification, and it took months to recoup that cost. That’s why I always start every conversation with a customer by asking two questions: how many eggs do you need to process per hour, and how many people will be working on the line next to the machine? Those two answers are the biggest factors in figuring out which machine will work best for you, including noise level.
At the end of the day, noise level is about more than just comfort—it’s about your team’s health, your operational efficiency, and your peace of mind. A quiet machine means your workers are less fatigued at the end of a shift, which reduces errors in egg handling or quality control. It also means you don’t have to spend extra money on hearing protection, sound enclosures, or OSHA-related modifications. When you partner with us, we don’t just sell you a machine—we walk you through every spec, including noise level, and we help you choose the right model for your operation, so you don’t have to deal with surprises after installation.
If you’re in the market for an egg washing machine and want to learn more about our noise levels, or if you’d like to get a custom recommendation based on your production volume and workplace layout, we’d love to chat. We can share real-world test data, connect you with references from similar operations, and answer any questions you have about compliance, installation, or maintenance. Don’t make the same mistake I saw that Texas customer make—ask the noise level question upfront, and choose a machine that works for your team as much as it works for your bottom line.
