聴能形成 I を基礎とし，より実際的な場面に即した音の感性の形成を目指す。各項目の訓練の前に、項目の解説を行うとともに、必要に応じて、デモンストレーションを行う。
音色の特徴，sharpness，roughness，fluctiation strength、協和性理論といった項目に関しては、特に詳細に説明する。
また，身の回りに存在する各種の音を意識してもらうために、サウンドスープの概念を説明するとともに，サウンド・エデュケーションを実施する。

Technical listening training (TLT) is a systematic training program designed to improve auditory sensitivity. TLT was developed at the Department of Acoustic Design, Kyushu Institute of Design (later joined to Kyushu University). Through this program, students can obtain the necessary auditory sensitivity before gaining work experience on the job. TLT provides a wide variety of experiences, so that students can obtain auditory sensitivity associated with various fields and easily adapt to new auditory environments after graduation.
First-semester sophomores are enrolled in Technical Listening Training II as an advanced course of TLT I. This class consists of more practical training tasks. This course further explores the identification of enhanced frequency of colored music. In addition, students receive training in identification of low-cut and high-cut frequencies. As an advanced identification training exercise involving the sound pressure level difference, students practice the identification task of sound pressure level difference of one part of a music ensemble. This training simulates control of the mixing console used by recording engineers. Further tasks are identification of spectrum envelope slope using a music excerpt, reverberation time, sound and noise ratio and quantizing bit rates.
The class includes lectures on sound color, concept of auditory filter, consonance theory. Students also learn sound quality metrics; sharpness, roughness, and fluctuation strength. Students are expected to understand the relationship between physical properties of sounds and auditory perception. This understanding contributes to further effectiveness of TLT. Furthermore, they learn the concept of soundscape and brush up sensitivity to everyday sounds through sound education program.
