| 3D46.00 | Tuning Forks | | |
| 3D46.15 | tuning fork sets | S-2g | Various sets of tuning forks. |
| 3D46.16 | tuning fork | PIRA 1000 | |
| 3D46.16 | tuning fork | Disc 10-03 | Use a microphone and oscilloscope to display the waveforms of 256, 512, and 1024 Hz tuning forks. |
| 3D46.20 | tuning forks | S-110 | Strike two tuning forks. Hold one against the table and the other in the air. When the first is no longer audible, hold the second on the table. |
| 3D46.21 | tuning forks | S-55 | Compare losses of tuning forks of steel and alloy, on and off a resonator box. |
| 3D46.22 | adjustable tuning fork | PIRA 1000 | |
| 3D46.22 | adjustable tuning fork | Disc 10-04 | Adjust masses on each tine of a large fork and show the waveform on an oscilloscope. Mistuned forks damp quickly. |
| 3D46.25 | modulation of sound waves | 19-9.3 | Two tuning forks of slightly different frequencies mounted on resonant boxes couple when the amplitude is varied by an oscillating barrier between them. |
| 3D46.30 | low frequency tuning fork | Sh-4 | Tuning fork motion can be studied with a large fork. |
| 3D46.31 | project a tuning fork | S-51 | Stroboscopically shadow project a vibrating tuning fork on a screen. |
| 3D46.40 | vowel tuning forks | Sf-2 | A set of tuning forks made to give sounds that sound like the vowels. |
| 3D46.45 | quadrupole nature of a tuning fork | Sc-3 | Hold a tuning fork close to the ear and rotate it. |
| 3D46.90 | frequency standard tuning forks | AJP 28(8),ix | Driven precision tuning forks of 400 and 100 Hz are used as secondary frequency standards. |
| 3D46.90 | Electronically driven tuning fork | AJP 28(5),505 | A tube circuit for driving a tuning fork. |
| 3D46.90 | electrically driven fork | S-56 | A vacuum tube circuit for driving tuning forks. |
