When sounding a pole for decay, starting at ground level and working upward is recommended.

• A. True
• B. False
• C. Only when poles are seasoned
• D. Only with supervision

Answer: (B)

Sounding a pole for decay is about listening for changes in tone when you tap the wood to detect hollow or rotten sections. The best approach is to start at the top of the pole and work downward. Beginning at ground level and moving upward can mix in effects from moisture and soil contact near the base, which can mask or mimic hollow sounds and cause you to miss decay higher up. By starting up top and proceeding downward, you get a clearer, more consistent baseline and you can identify any weak sections as you go, making the test more reliable and safer to act on. The method doesn’t depend on whether the pole is seasoned or on having supervision; those factors don’t change how you perform the sounding technique.
