Does the bell-like sound used in acapella chants fall under the prohibition of bells mentioned in the hadiths, and is it considered among the forbidden musical instruments?

The second is sounds processed with computer programs to resemble musical instruments or the melodious sound of a bell, and its ruling is the same as that of forbidden musical instruments.
