AC/DC Brian Johnson might return on stage sooner than expected after he revealed that he is responding well to a new in-hearing device.

Johnson took a time off from performing on stage due to a hearing problem. Guns N’ Roses frontman Axl Rose has been temporarily filling in as Johnson’s replacement while AC/DC is on its “Rock or Bust” world tour.

According to Entertainment Weekly, Johnson recently tried Stephen Ambrose’s ADEL hearing technology, and the rock band member said “it works” for him.

“It works,” Johnson said of Ambrose’s hearing technology in a statement shared on Facebook. “It just totally works and you can’t argue with that. I was really moved and amazed to be able to hear music again like I haven’t heard for several years now. I can’t wait for it to be miniaturized so I can use it in every situation from normal communication, going out to noisy restaurants, [and] performing live music on stage,” he added.

Earlier this year, Brian Johnson was forced to take a backseat after his doctors told him that he could completely lose his hearing if he continued to perform with the band, MusicFeed noted.

Despite the hearing problem, Johnson had stressed that he will not retire. EW quoted him saying: “My doctors have told me that I can continue to record in studios and I intend to do that … I am hoping that in time my hearing will improve and allow me to return to live concert performances. While the outcome is uncertain, my attitude is optimistic. Only time will tell.”

Ambrose suggested the hearing technology to Brian Johnson and posted a video on YouTube  inviting the AC/DC member to try it. Ambrose also claimed to have introduced the in-ear monitor to Guns N’ Roses back in 1990. The in-ear technology specialist further explained that the technology absorbs sounds that could damage the ear and can also bring back hearing to people who “are profoundly deaf”.

Meanwhile, Axl Rose earlier expressed interest to continue working with AC/DC in the future. In an interview with AC/DC’s guitarist Angus Young, he said: “We’re committed to finishing this tour, so that’s been our main goal. Axl helping us – I know he’s very excited. He keeps saying, can he do more [shows]. But we don’t know at the end. This tour, which we were committed to, we want to finish it.”

AC/DC also recently released the rescheduled dates for the 10 U.S. concerts which were postponed in March.
