PA 5 hand-held pediatric hearing screener – this uses three different stimuli (pure tone, narrow-band noise and warble tone) across frequencies of 500, 1000, 2000 and 4000 Hz. To elicit a response from a neonate. It’s more frequency specific.
Neonatal hearing screener – wide-band frequency @ 60 dB and 90 dB (this can detect in neonates moderate to severe hearing loss)
