A sonometer is an audiometer. A measuring instrument used to measure the sensitivity of hearing.
The sonometer wire is usually made up any material which is non-magnetic in nature.
Here's a tip: You don't even need a sonometer. The frequncy of DC is zero.

A sonometer is an apparatus for investigating the vibration of a string or wire under tension. The equipment allows the length of the string and its tension to be varied. See Wikipedia entry 'sonometer' for more details

Tuning forks should be struck gently and put over sonometer boxes gently due to the fragile nature of the tuning fork and the sonometer box. The tuning fork is a metal rod with two prongs that vibrate at a specific frequency when struck. This vibration can be damaged or distorted if the tuning fork is struck too hard. Similarly, the sonometer box is a box filled with metal strings or wires, and if the tuning fork is placed too hard or too quickly, the metal strings can be damaged or distorted. Gently striking and placing the tuning fork over the sonometer box is also important for accurate results. If the tuning fork is struck too hard, the frequency of the resulting vibration will be higher than desired, and if the tuning fork is placed too hard or too quickly onto the sonometer box, the vibrations will be distorted and the resulting frequency will not be accurate. In conclusion, tuning forks should be struck and placed over sonometer boxes gently in order to protect the fragile nature of both the tuning fork and the sonometer box, as well as to ensure accurate results.
