¿79 dB es un nivel de ruido excesivo para una aspiradora?

You aren't crazy at all. If your vacuum sounds like a jet engine taking off in your living room, you're experiencing what many Reddit users vent about on r/VacuumCleaners: modern vacuums can genuinely feel overwhelmingly loud.

While sounds at or above 85 dB are officially recognized as the threshold where hearing damage begins with prolonged exposure, a vacuum hitting 79 dB (or higher) is uncomfortably loud for an indoor space—even if it technically sits below that danger line.

How Decibels Add Up

To put those numbers into perspective, decibels do not scale linearly—they use a logarithmic scale where every increase of 10 dB represents a doubling in perceived loudness:

• 60 to 70 dB: Normal conversation, a humming refrigerator, or a dishwasher running. Easy to talk over without raising your voice.

• 75 to 80 dB: Heavy city traffic, a noisy restaurant, or a powerful vacuum cleaner. At this level, speech starts getting drowned out.

• 85 dB and above: Power tools, lawnmowers, and heavy machinery. Prolonged exposure here requires hearing protection.

Because a 79 dB vacuum sits right on the edge of the "very loud" category, running it for 30 minutes across your house can leave your ears ringing or feeling fatigued.

Why Are Some Vacuums So Loud?

High suction power often requires high-RPM motors, which inherently create more noise. However, cheaper plastics, poor acoustic insulation, and high-velocity air rushing through narrow channels can turn an ordinary cleaning session into an auditory assault.
