you can't compare a 5-10 minutes hearing test with frequencies with sounds you are used to hearing -
sound with musical instruments , or street sound is natural , as far as I am concerned , hearing tests should be given with everyday sounds and various levels of hearing , rather than tone frequencies ,
- if you can hear a record playing music at normal volume levels , you are not hearing impaired , if you do not , but only at a louder volume , you are hearing impaired
