Talk show producers have said for years that they need a good audience to make a good episode. Many of the shows bring audience members into the studio an hour before showtime. For some shows, music is pumping at eardrum-splitting volumes, the better to whip fans into a frenzy and get them primed for big reactions live on air.

Now those big laughs and cheers will be silenced for the foreseeable future.

The syndicated talk shows “Live With Kelly and Ryan” and “The View” both barred studio audiences beginning on Wednesday because of fears surrounding the coronavirus. Other talk shows, such as “Dr. Phil” and “The Wendy Williams Show,” have made the same decision, joining Los Angeles-based game shows, like “Wheel of Fortune” and Jeopardy!,” that said this week that they would forgo studio audiences.

“That shouldn’t stop everyone from watching at home,” Mr. Seacrest’s co-host, Kelly Ripa, said on Wednesday. “Because let’s face it: You can’t go anywhere else!”

NBC’s “Late Night With Seth Meyers” and Comedy Central’s “The Daily Show With Trevor Noah” were among the New York-based late-night shows that said they would film without studio audiences starting on Monday. Two weekly late-night shows — “Last Week Tonight With John Oliver” on HBO and Samantha Bee’s “Full Frontal” on TBS — said they would forgo audiences, too.

“Per guidance from New York City officials, the company is hoping to do its part to help to decrease the rate of transmission in our communities,” NBC said in a statement.
