This video explores the noise levels of a Deuce and a Half (M35) military truck. While the speaker's phone decibel meter app had limitations, readings indicated around 85-90 decibels when tooling around town and at least 90 decibels at highway speeds (45-50 mph). This level necessitates hearing protection for extended periods according to OSHA standards, which allow for 8-6 hours of exposure at these levels respectively. The video also compares the noise to an F250 diesel and a Ford Fiesta, highlighting the significant difference.

Quick Summary

The Deuce and a Half (M35) truck produces significant noise, registering between 85-90 decibels around town and at least 90 decibels at highway speeds (45-50 mph). According to OSHA, 90 decibels allows for only 6 hours of exposure per day, making hearing protection essential for extended driving periods.

Frequently Asked Questions

How loud is a Deuce and a Half truck?

A Deuce and a Half (M35) truck typically registers between 85 and 90 decibels when driven around town. At highway speeds of 45-50 mph, the noise level reaches at least 90 decibels, potentially higher. This level necessitates hearing protection for extended periods.

What are the OSHA guidelines for noise exposure in a Deuce and a Half?

OSHA standards permit 8 hours of daily exposure at 85 decibels and 6 hours at 90 decibels. Given the Deuce and a Half's noise levels, prolonged driving, especially at highway speeds, requires appropriate hearing protection to avoid potential damage.

How does the noise of a Deuce and a Half compare to other vehicles?

The Deuce and a Half is significantly louder than a 1997 Ford F250 diesel (mid-70s to low 80s decibels) and a Ford Fiesta (68-72 decibels). The F250 is generally safe for hearing without protection, while the Fiesta is very quiet.

Can a phone app accurately measure the noise of a Deuce and a Half?

Phone decibel meter apps can provide an estimate of noise levels, but their accuracy can be limited, especially with cheaper models that often cap out at 90 decibels. For precise measurements, professional equipment is recommended.
