How Driving With the Windows Open Affects Your Hearing Health


Woman and man driving with windows down in car.

Is driving with the windows open detrimental to your hearing? Is it more fuel-efficient? Should you opt for closed or open windows while driving? Here’s a fresh perspective on these questions.

Picture this: It’s a serene early morning, the clock ticking at 7:45 AM. With the highway almost deserted, you cruise along at a comfortable 55 MPH, savoring the cool breeze through your open windows. On such a picturesque day, running the car’s air conditioner seems unnecessary, doesn’t it? After all, why waste precious gas?

But here’s the question: does driving with the windows down pose risks to your hearing?

What the research says about driving with open windows

Think it’s not that loud? Researchers in the UK conducted experiments with various vehicles, from Mazdas to Aston Martins, during non-peak hours at speeds of 50, 60, and 70 MPH.

Their findings were consistent: irrespective of the vehicle model or speed, driving with windows down exposed the driver to a near-constant noise level of 89 decibels.

Does this noise level pose a risk of permanent hearing damage?

Indeed, exposure to 85 decibels over an 8-hour period can lead to permanent hearing loss.

In heavy traffic conditions where exposure exceeds 100 decibels, hearing damage can occur within a mere 15 minutes.

What contributes to increased noise with open windows?

While your car might seem noisy, several factors can exacerbate the decibel levels.

Engine and vehicle types

Most gas engines produce around 85 decibels of noise due to the rapid explosions in their cylinders, accounting for roughly 80% of gas-powered vehicles. However, hybrids, electric cars, or smaller 4-cylinder engines may offer a quieter ride. Conversely, high-performance vehicles like Ferraris can generate over 100 decibels, especially in lower gears.

Wind resistance

The whooshing and whistling sounds caused by wind passing over your vehicle can significantly add to the overall noise level, even in relatively quiet cars. Studies have shown that cyclists face around 85 decibels of wind resistance at just 15 MPH, escalating to 120 decibels at 60 MPH. Given that cars experience even greater wind resistance, driving with windows down can indeed impact your hearing.

Traffic amplifies noise

Each passing vehicle, even on multi-lane highways, contributes to noise amplification. Besides the engine noise, you’re subjected to the wind resistance from passing vehicles, further increasing overall noise levels.

How to mitigate risks and ensure safe driving practices

If you enjoy driving with windows down, consider these steps to minimize hearing loss risks:

  • Take breaks during long drives, alternating between windows up and down.
  • For convertible owners, closing the windows while keeping the top down can reduce sound to safer levels.
  • Utilize smartphone apps to monitor noise levels in regular traffic conditions (never while driving).
  • Keep windows up in heavy traffic to avoid prolonged exposure to loud noises exceeding 100 decibels.
  • Avoid drowning out traffic noise with loud music, as it can exacerbate hearing damage.
  • If riding a motorcycle or bicycle, invest in helmets designed to mitigate traffic noise.
  • Regularly monitor your hearing health, especially if you’ve been habitually driving with windows down.

In summary, driving with windows down exposes you to various sources of noise, including engine and wind noise, potentially impacting your hearing health. By adopting precautionary measures, you can safeguard your hearing while enjoying the freedom of open-road driving.

Find a hearing specialist near you if you are concerned about noise-related hearing loss.
